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 90 kHz and an LCL output filter to reduce the size of the magnetics. 1 shows the electrical circuit of the T-type inverter. Fuji Electric's new generation IGBT module (V series) using RB-IGBT technology is applied for the converter, due to its higher efficiency from conventional IGBTs to reduce switching losses on the. . A schematic block diagram of the inverter switching block with corresponding switch arrangement and naming, is given in Figure 2. The designed inverter is used in a battery-based energy system (BESS) for power conversion optimization in applications to. .
