Description

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.

Features
  • Rated nominal input of 380 - 400VAC peak, with DC output of 800V
  • Maximum 10-kW, 10-kVA output power at 400-VAC 50- or 60-Hz grid connection
  • High-voltage (1200-V) SiC MOSFET-based fullbridge AC/DC converter for peak efficiency of >97%
  • Compact filter by switching rectifier at 50 kHz
  • Isolated driver ISO5852S with reinforced isolation for driving high-voltage SiC MOSFET and UCC5320S for driving middle Si IGBT
  • Isolated current sensing using AMC1301 for load current monitoring
  • TMS320F28379D control card for digital control
