1000 W Step-Up DC-DC Converter Powers Vehicle Electronics

The Flexistax® D1001 DC-DC converter module is the latest addition to Powerstax’s portfolio of power solutions for next-generation vehicles. Based on the company's proprietary, field proven F501 brick technology, this 1,000 W rated module is capable of supporting typical system efficiency levels of 86%.

It exhibits a high degree of operational flexibility, with an input voltage range covering 10 VDC to 36 VDC and a choice of 12, 13.8, 15, 24, 28, 32, and 48 VDC standard outputs. These attributes mean that the modules are highly optimized for the electric or fuel cell powered vehicle market (either in commercial or military use).

A 4-channel boost converter enables DC voltages to be stepped up or down as required. This boost converter delivers a non-isolated bus voltage that drives the two parallel configured brick converters - so that the regulation, isolation (2200 VDC) and stability (<2% peak-to-peak ripple) needed by modern, sophisticated electronics can be fully realized. Conduction cooled using a baseplate, the D1001 has an operational temperature range that spans from -25 °C to +85 °C. With a compact form factor measuring just 238 x 145 x 30.85 mm (9.4  x 5.7  x 1.2 in.), this open construction unit can be cold wall mounted - allowing the baseplate temperature to be kept at 100°C or below without the need for complex, expensive thermal management.

An array of protection mechanisms are incorporated into the module to ensure functional longevity. These include an I2C temperature sensor to prevent overheating and an automatic reverse polarity to safeguard against mixing up of power connections. In addition to specification in automotive designs, these DC-DC converter products are also highly suited to implementation in remote battery, generator or fuel cell powered sites (such as mobile infrastructure and industrial monitoring stations), back-up power systems, as well as various up-mast applications. They are fully compliant with the EN60950-1 safety standard.
