This reference design provides an overview on how to implement a bidirectional three-level, three-phase, SiC-based active front end (AFE) inverter and power factor correction (PFC) stage. The design uses switching frequency up to 90kHz and an LCL output filter to reduce the size of the magnetics. It provides an explanation of the typical workflow of the PLECS Embedded Coder, using Texas Instruments (TI) C2000 MCUs. Such a system can be typically found in small industrial photovoltaic facilities, which are directly connected to the low voltage power grid. The presented system implements a dual-stage conversion structure, using a boost DC/DC. . Three-phase inverter reference design for 200-480VAC drives (Rev. This design uses the C2000. .
