Description

This reference design provides a design template for implementing a three-level, three-phase, silicon carbide/gallium nitride (SiC/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%. This design is modular in construction, making it configurable to work with SiC or GaN power devices with the same filter stage.

Features
  • Three-level power stage for three-phase inverters/PFCs using 650-V rated SiC/GaN switches in a 800-V system
  • Novel on-board protection implemented using CLB of C2000 to get real-time safety operation with no extra cost
  • Optimized control scheme needs only 6 PWMs from MCU vs. 9 PWMs for standard implementation
  • Shunt-based current sense implemented for high accuracy and linearity over temperature
  • High-power density due to high-switching frequency (100 kHz) and high efficiency
