Description

Bi-directional 3-phase 3-level T-type Active Front End can enable high efficiency and reduced size of the power stage in applications such as solar inverters, energy storage systems and bi-directional on-board chargers.

This design illustrates a method to control the power stage using either a C2000™ TMS320F28377D or TMS320F28P650DK or TMS320F280039C real-time MCU.

Software Version SDK Release Changelog
v1.00.00 3.02.00.00 First release, on F2837xD devices in C2000Ware Digital Power SDK
v1.01.00 4.00.00.00 Changes & Enhancements:
  • Change compiler version (from v20.2.1 to v21.6.0)
  • Add source-lookup path for driverlib
v1.02.00 4.01.00.00 Features & Enahancements:
  • Added DC bus voltage feed-forward for PFC and inverter current loop control.
