Reference Designs

This reference design provides an overview on how to implement a three-level: three-phase: SiC-based AC/DC converter with bi-directional functionality. A high switching frequency of 50 kHz reduces the size of magnetics for the filter design and as a result a higher power density. SiC MOSFETs with switching loss enable higher DC bus voltages of up to 800V and lower switching losses with a peak efficiency of >97%. This design is configurable to work as a two-level or three-level rectifier. For design information on the DC/AC implimentation: see TIDA-01606.The system is controlled by a single C2000 microcontroller (MCU): TMS320F28379D: which generates PWM waveforms for all power electronic switching devices under all operating modes.
