Interoperability Lab Begins Multivendor PoE Testing

Early this month, several members of power over Ethernet (PoE) consortium participated in a group test period at the University of New Hampshire’s InterOperability Laboratory (UNH-IOL). Engineers from these participating companies, which included Avaya, Cisco Systems, 3COM, Linear Technology, PowerDsine, and Texas Instruments (TI), along with student engineers, executed the PoE Consortium’s IEEE 802.3af tests.

In essence, the interoperability testing was performed on a complete matrix of powered devices (PDs) and power sourcing equipment (PSE). Primarily, the focus was on physical layer testing for these two product groups. On the PSE side, detection, classification, and power application functions of the device under test (DUT) were examined. According to test engineer Jeremy Kent of UNH-IOL, the unit is tested to ensure that it sends out proper detection and optional sequences, and falls within the constraints of the standard with regards to pulse timing, voltage and current levels, and noise levels. In addition, several other power supply output parameters are outlined in the PSE test suite.

On the PD end, the unit was tested to see if it presents a valid detection signature when it is requesting power over the interface and that it provides classification information about its power requirements to the attached PSE. Furthermore, tests were done to see if the PD under test becomes operational after it receives power.

”We put each PSE and PD pair in a real world environment, attached over a 100 m cable. Power is applied to the link segment, and data is exchanged between the two devices to ensure data integrity and operation,” said Kent.

PowerDsine, for instance, tested its Power over LAN Dual In-line Memory Module (PoL-DIMM) technology, which is based on its embedded IEEE 802.3af-compliant Power over LAN ASIC. It also tested its Power over LAN 3000 series of midspans. In addition, TI’s power interface switch TPS2370 and power sourcing equipment manager TPS2383 were tested for interoperability.

PoE Consortium Manager Gerard Nadeau said, “Parametric testing has improved extensively since the last GTP and will continue to advance. Feedback from members participating in the test event will be used to further develop our test procedures and test suites. As a result of this GTP, the number of powered devices in the consortium’s test bed has more than doubled, resulting in a more comprehensive matrix of interoperability testing.”

The UNH-IOL continues to look for new members to expand its interoperability test bed. Another Power over Ethernet GTP will be held later this year.

Signs Point to Communications Power Recovery

In January of this year, Darnell Group forecast that after yet another decline in 2002, the global communications power market was poised for a recovery in the fourth quarter of this year and was expected to grow from $4.410 million in 2003 to $5.774 million in 2008, a compound annual growth rate (CAGR) of 5.5%.

All indications are that the company’s forecast was correct.

Signs of the impending recovery are already appearing. As more users flock to data services, carriers will need to expand and upgrade their networks accordingly. Capital equipment spending is projected to begin as soon as the fourth quarter of 2003 or early 2004. Supply and demand in the equipment industry are achieving a "better balance," as spending rates by service providers approach the historical average of about 15% of their revenue, compared to 30% at the peak in 2000 and steep drop-offs in the following years. More than ever, precise targeting will be critical. In terms of geographic regions, Network Infrastructure will dominate growth in Asia and China while several other regions will see near-term growth dominated by Enterprise Equipment sales. Wireless infrastructure activity will continue to pick up in the Asia Pacific and Europe regions. The fixed-line and cellular penetration rates in China point to a significant communications equipment industry growth opportunity for years to come. In most instances, spending to provide broadband applications for the enterprise will drive Network Equipment sales while spending on computer-telephony integration (CTI) is expected to drive Enterprise Equipment sales. The Semiconductor Industry Association sees strong consumer demand for broadband services such as DSL and cable products.

As the recovery takes hold, the unit market is expected to experience a CAGR of 11.2%, from 156,600 units to 265,600 units over the period from 2003 to 2008. But growth won’t be linear going forward. Due to increasing competition and price cuts, the dollar market may still experience negative growth from 2003 to 2004, even as the unit market grows modestly during the same period. After 2004, growth in dollar sales will slowly start accelerating. In addition to forecasting the dollar and unit market growth for five power system segments (Micro, Small, Medium, Large and CO-Class), this report includes a detailed pricing model for dc power systems.

This in-depth analysis provides detailed dollar, unit and pricing forecasts of the anticipated recovery across regions and equipment segments.

150W Switcher

Taiyo Yuden Inc.’s new PAS150 is the first model in the company’s new PAS Series of affordable, passive PFC-based, switch mode power supplies for 1U-height single-output applications. The PAS150 provides tremendous economic benefits to OEMs by employing passive PFC technology—vs. the more complex, less reliable, active PFC technology that now provides unnecessary functionality at higher cost, thanks to the recent declassification of many Class D end devices to less stringent Class A standards per EN61000-3-2 harmonic distortion standards.

The PAS150 switcher not only meets all Class A PFC requirements, but also provides greater reliability and higher MTBF (mean time between failure) through use of fewer components. Furthermore, the relative cost per Watt of a passive PFC switcher like the PAS150 is significantly less than a comparable switch mode power supply employing active PFC techniques.

In operation, the PAS150 switcher provides a universal 115/230Vac input selection and a single output of 150W continuous power. The user can select one of several factory-set output voltages, including 3.3V, 5V, 12V, 24V, and 48V. The PAS150 switcher features optional current-sharing capability for 1+1 redundancy with no special interconnection requirement. Other options include remote on/off, and droop or single-wire current sharing with OR-ing diodes. The standard unit provides superb heat dissipation, and also offers an optional fan with its own 12Vdc supply.

Discrete Power Semiconductor Supplier Eyes SiC Diodes

Aiming to tap the benefits of zero-recovery current and negligible switching losses with high temperature capability of silicon carbide (SiC)-based Schottky diodes, discrete power semiconductor supplier Advanced Power Technology (APT) has inked a licensing deal with Cree Inc. Under this agreement, APT will purchase Cree’s SiC zero-recovery Schottky diode dies, and produce packaged devices and modules under its own brand name.

Using alternative packaging and innovative engineering, APT intends to address market segments not served by Cree. In addition, it will explore military, industrial, communications, semiconductor equipment, and medical applications for its SiC Schottky diodes and other designs created using these high-performance diodes. According to Glenn Wright, APT’s vice president of marketing and business development, APT intends to explore applications where low losses are critical and cost is warranted. This marks APT’s first offerings in SiC, said Wright.

In addition to standard plastic packages, the SiC diodes will be available in hermetic and high-performance packages. The plastic packages will be assembled in the Philippines, while the hermetic and advanced packages will be produced in the company’s facilities in Bend, Ore., and Bordeaux, France. APT will use its expertise in high-power semiconductor manufacturing to offer multidie parallel discrete devices in TO-220, TO-247, D2, D3, and SOT-227 packages, as well as hermetic packages with and without military screening. The dual-die packages will offer common cathode configuration. Furthermore, the supplier will offer the latest generations of MOSFETs and IGBTs built in combination with the SiC Schottky diodes in both boost and buck configurations. Power modules and other custom designs using the SiC zero recovery Schottky diodes will also be offered.

All SiC-based diodes in plastic packages will be rated at 175°C, while hermetic and high-performance packages will be rated at higher temperatures. Due to higher band gap property, these devices will offer extremely low leakage at elevated temperature. Other features include high thermal conductivity, faster switching speed compared to silicon diodes, and 600V to 1200V breakdown capability.

APT is already in sampling mode of 6A and 10A SiC Schottky diodes in plastic packages with plans to take these into production in the fourth quarter.

Fairchild to Convert All Products to Lead-Free Finish Packages

Fairchild Semiconductor has announced that it has initiated conversion of all products to lead-free (Pb-free) finish packages. Conversion will continue through the remainder of this year, with completion expected by June 2004.

Fairchild’s lead-free packages meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B, are compliant with the European Union requirements that will take effect in 2005, and meet additional conditions delineated by key customers.

Fairchild launched its Pb-free initiative to provide its customers with lead-free package finishes, responding to concerns about the environmental impact of lead, historically used in solder finishes and lead coating in electronic components.

JEDEC requires moisture sensitivity level (MSL) certification using reflow peak temperature testing to 250°C. This higher temperature testing is required to ensure that packages attach properly to printed circuit boards. A majority of Fairchild’s surface-mount lead-free packages have been tested to a peak reflow temperature of 260°C to provide customers with additional reliability assurance.

The primary lead-free finish used by Fairchild is pure matte tin, providing stable plating highly compatible with widely used tin-lead solder processes. It’s also compatible with Pb-free board assembly processes, such as those using tin-silver-copper (SnAgCu) solders.

ABB Motors/Drives Used to Attempt Electric Land Speed Record

ABB drives and motors, used to power loads in virtually all industry applications around the world, are providing the power conversion needed for the main drive system in a new challenge to the world electric land speed record. ABB's new ACS800 ac drive converts the 600Vdc output from four packs of lead-acid batteries in e=motion, a new electric car designed in Britain, for the two 50 hp (40kW) IP23 through-ventilated ac motors that power the car. ABB's system will enable e=motion to travel at over 300 mph, well in excess of the top speed of a Formula One car.

Powered by the dc batteries and controlled by the ACS800 ac drives that feature the company's exclusive Direct Torque Control (DTC) motor control algorithm, the two motors already have propelled the e=motion car to 146 mph during testing. This unofficially broke the 139 mph U.K.-record for the fastest speed traveled by an electric vehicle. The car will be moved to Tunisia in September and the vehicle's designers, Mark Newby and Colin Fallows, will attempt to set the new world electric land speed record. A U.S. team holds the current world record of 247 mph.
