This reference design demonstrates control of HEV/EV traction inverter and bi-directional DC-DC converter by a single TMS320F28388D C2000™ real-time MCU. The traction control uses a software-based resolver to digital converter (RDC) driving the motor to a high speed up to 20,000 RPM. The DC-DC converter uses peak current mode control (PCMC) technique. An ASIL decomposition based functional safety concept for the system has been assessed with TÜV SÜD to demonstrate system level safety integrity level up to ISO 26262 ASIL D for representative safety goals.
