Busbars suit electric and hybrid vehicles, solar power inverters

Rogers Corporation’s Power Distribution Systems Division introduces a new product line for power electronics applications called RO-LINX PowerCircuit busbars. The PowerCircuit products are designed to meet the growing power distribution demands in electric vehicle (EV) drives, hybrid electric vehicle (HEV) drives, and related charging systems. Other applications include solar power inverters, uninterruptable power supplies (UPS), and industrial motor drives. RO-LINX PowerCircuit busbars bridge the divide between printed circuit board (PCB) power distribution components and higher power laminated busbar systems, such as the RO-LINX laminated busbar products.

RO-LINX PowerCircuit busbars combine the performance features of power PCBs and laminated busbars and deliver excellent thermal management. Unlike 2-D power PCBs, PowerCircuit busbars can be made in three dimensions to reduce weight and size, and to conform to specific engineering designs to maximize efficiency. In addition, PowerCircuits eliminate assembly steps for the end user reducing complexity and sources of error.

Whereas traditional power PCBs can handle up to 100 A current due to limited conductor layer thickness, laminated busbars serve much higher power applications, generally at current levels from 500 A to more than 1,000 A. RO-LINX PowerCircuit are also suited for applications at current levels from 100 to 500 A, such as industrial variable frequency drives and HEV or EV motor drives. Furthermore, RO-LINX PowerCircuit busbars can be combined with industrial mounting of functional components such as capacitors, sensors, and IGBTs.

The new busbars incorporate a closed mold design, using materials engineered for high performance in applications subject to high vibration and temperature cycling, such as in EV or HEV drives. 3D designs are well suited for medium to high volume assembly and most soldering processes. The RO-LINX PowerCircuit busbars are also compatible with a number of different interconnect systems, including press fit, bolted-on, riveted, and common soldering methods.

RO-LINX PowerCircuit busbars offer excellent thermal management properties and achieve high power efficiencies while minimizing switching losses and reducing dangerous partial discharge and transients. They are suited for use at lower to medium voltages, to about 690 V, and are compact and lightweight enough to support the latest power electronics designs in EVs and HEVs, and other mobile applications.
