Motor Drive
Electric/Hybrid propulsion systems and electrification of other non-propulsion vehicle motors are requiring large investments. Automotive OEMs and suppliers seek to achieve optimized efficiency and control characteristics for all vehicle motors. Therefore, power electronics converters, inverters and drives are used in new vehicles.
Power electronics systems utilize power semiconductors in various half-, full (H)-, or cascaded H-bridge designs to provide optimized control and efficiency of propulsion and other motors. Complex Vector FOC or direct torque control systems, including those that monitor and control power flow based on analysis of a single device switching period, are used. Motor speed and torque feedback signals provide important information for control and power flow. All inverter subsection, control system, motor feedback, and system level devices need extensive validation, often under complex dynamic conditions.
