TIDM-02009 ASIL D Safety Concept-Assessed High-Speed Traction, Bi-directional DC/DC Conversion Reference Design
This reference design demonstrates control of HEV/EV traction inverter and bi-directional DC-DC converter by a single TMS320F28388D real-time C2000â„¢ 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 with phase-shifted full-bridge (PSFB) topology and synchronous rectification (SR) scheme. The traction inverter stage uses silicon carbide (SiC) power stage, driven by UCC5870-Q1 smart gate driver. PCMC waveform is generated using state-of-the-art PWM module and built-in slope compensation in the comparator sub-system (CMPSS). An ASIL decomposition based functional safety concept for the system has been assessed with TÃœV SÃœD to demonstrate system level safety integrity level up to ISO 26262 ASIL D for representative safety goals.

PSFB Control Using C2000 Microcontrollers Application Report
This application report presents the implementation details of a digitally controlled PSFB system implemented on the high voltage phase shifted full bridge (HVPSFB) kit from Texas Instruments. This kit converts a 400 V DC input to a regulated 12 V DC output and is rated for operations up to 600W. Both peak current mode control (PCMC) and voltage mode control (VMC) implementations are described.
TIDA-BIDIR-400-12 Bidirectional DC-DC Converter
This document presents the details of this microcontroller-based implementation of an isolated bidirectional DC-DC converter. A phase-shifted full-bridge (PSFB) with synchronous rectification controls power flow from a 400-V bus or battery to the 12-V battery in step-down mode, while a push-pull stage controls the reverse power flow from the low-voltage battery to the high-voltage bus or battery in boost mode. This design is rated for up to 300 W of output power in either mode.
