Description

This reference design demonstrates a method to control a continuous conduction mode (CCM) Totem pole power factor correction converter (PFC) using a C2000™ TMS320F280039C or TMS320F280049C real-time MCU.

This design is bidirectional and works as inverter in grid connected (current controlled) mode. The converter is designed to support a maximum input current of 16-ARMS with peak power of 3.6 kW. The LMG3522 top-side cooled GaN device with integrated driver and protection enables higher efficiency while reduces power supply size and complexity.

F28003x or F28004x from C2000 realtime MCU can be used for all the advanced controls such as fast relay control and reverse current flow protection. The design also supports adaptive dead time for efficiency improvements, input cap compensation scheme for improved power factor at light loads, and non-linear voltage loop to reduce voltage spikes under transient in PFC mode.
