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 C2000™ 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 TÜV SÜD 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.
TIDM-02014 High-power, high-performance automotive SiC traction
inverter reference design
TIDM-02014 is a 800-V, 300kW SiC-based traction
inverter system reference design developed by Texas Instruments and Wolfspeed
provides a foundation for design engineers to create high-performance,
high-efficiency traction inverter systems and get to market faster. This solution
demonstrates how the traction inverter system technology from TI and Wolfspeed
improves system efficiency by reducing the overshoot in available voltages with a
high-performance isolated gate driver and real-time variable gate drive strength
driving the Wolfspeed SiC power module. TI's high-control performance MCUs featuring
tightly-integrated, innovative real-time peripherals enable effective traction motor
control even at speeds greater than 20,000 RPM. Fast current loop implementation
helps minimize motor torque ripple and provides smooth speed-torque profiles. The
mechanical and thermal design of the system is provided by Wolfspeed.
