IC revisionE1

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

  • Power stage for three phase inverters/PFCs usingSiC/GaN switch
  • 650-V rated switches in 800-V system (due tothree levels)
  • Novel on-board protection implemented using CLBof C2000
  • Iso-dual channel driver supports high frequencyoperation (100KHz)
  • Shunt based current sense (high accuracy andlinearity over temperature)

Typical applications

  • Solar String Inverters, Solar Central Inverters, Energy storage power conversion system (PCS)
