11-kW, bidirectional, three-phase ANPC based on GaN reference design


Design files


This reference design provides a design template for implementing a three-level, three-phase, gallium nitride (GaN) based ANPC inverter power stage. The use of fast switching power devices makes it possible to switch at a higher frequency of 100 kHz, reducing the size of magnetics for the filter and increasing the power density of the power stage. The multilevel topology allows the use of 600-V rated power devices at higher DC-bus voltages of up to 1000 V. The lower-switching voltage stress reduces switching losses resulting in a peak efficiency of 98.5%.

  • Power stage for three-phase inverters and PFCs
  • 600-V rated switches in 800-V system (due to three levels)
  • Novel onboard protection implemented using CLB of C2000
  • Iso-quad channel driver supports high-frequency operation (100 kHz)
  • Shunt-based current sense (high accuracy and linearity over temperature)

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
