Power Electronics and Controls Development

We have extensive experience in developing power electronic motor controllers, inverters, dc-dc converters and control software for a variety of applications to meet tough automotive requirements. Our electronics engineers have designed controllers in power ranges from 1 kW to 120 kW and voltages from 12 V to 800 V incorporating air, liquid, and hydrogen cooling. Features such as CAN communication, torque-based traction control, diagnostic capability, phase advance, sensorless control and enhanced thermal management come standard on most of our products. Several of our current products integrate the power electronics with the motor/generator using common shared housings and cooling systems.

Our power electronics and controls department has developed numerous proprietary design and analysis computer programs for controller design and analysis. One example is a detailed mathematical model of a motor controller that we have developed and refined over the last decade. This model accurately predicts the controller’s performance including losses and device operating temperatures over a wide range of environmental conditions. The analysis results from these models are utilized to size the hardware design requirements and controller’s cooling system. In addition to its proprietary design tools, our power electronics and controls department uses a variety of commercial software packages including P-CAD for schematic capture, PCB design and auto routing; Micro-Cap for electrical circuit analysis; Mathematica for system simulation; and Mathcad for system simulation.

We also have extensive capability and computerized tools for developing electric motor/generator control applications using digital signal processors (DSPs). DSPs have enabled us to broadly expand our motor control capabilities by utilizing more sophisticated algorithms. The utilization of DSPs allows us to design more compact hardware, translating into lower manufacturing costs. The software and DSP development tools we use include compilers, assemblers, linkers and source-level debuggers for developing applications on Motorola microprocessors and Texas Instrument’s DSPs.

Our power electronics development laboratory is outfitted with the latest fabrication, test and debug equipment and has the capability to build and test prototype analog and digital circuits and power systems.
