TIDM-02002: Reference Designs Using TI C2000 for Three-Phase Totem-Pole PFC and CLLC DC/DC Control

Part Number: TIDM-02002

Tool/software:

Hi,

We are currently considering whether it is possible to digitally control a power system consisting of a three-phase AC input followed by PFC and DC/DC conversion.

We are planning to use separate MCUs to independently control the PFC and DC/DC stages:

  • The PFC stage (from three-phase AC input) will use a totem-pole topology

  • The DC/DC stage will use a CLLC topology

To begin, we would like to gain a basic understanding of how to implement such control using TI’s C2000.

Could you please recommend any reference designs using TI C2000 that demonstrate three-phase totem-pole PFC control and CLLC DC/DC control?

Thanks,

Conor
