The traction inverter is the main power processing system in an electric vehicle. The real time control of this power processing block being a critical task, needs a microcontroller unit (MCU) with low latency peripherals and deterministic processing time.

PCB design of motor drive systems is not trivial and requires special considerations and techniques to achieve the best performance. Power efficiency, high-speed switching frequency, low-noise jitter, and compact board design are few primary factors that designers must consider when laying out a motor drive system.
