This reference design is comprised of four separate boards that intercommunicate. The following boards work in tandem to form this three-phase inverter reference design:
- A power board, comprising all of the switching device, LCL filter, sensing electronics, and power structure
- A TMS320F28379D control card to support the
DSP
- Three gate driver cards, each with two UCC21710 and two UCC5320 gate drivers
- A DC bus voltage measuring board (TIDA-01606 ISOHVCARD)
