3.2.2. Power Electronics Block Model

The power electronics block is a synthesizable model of the power electronics section of an EV charger. The blocks described in this section are models of an actual power stage you can find in any EV charger three-phase boost bidirectional AD/DC converter. It includes the following components:
  • Insulated Gate Bipolar Transistors (IGBT)
  • Diodes
  • High-voltage capacitors
  • Modeling of parasitic resistance and capacitance

The significance of modeling the power electronics in HDL and FPGA is to enable you to emulate your power stage in FPGA and fine-tune the controller parameters according to your system characteristics. In an actual design, the power electronics block is removed, and actual implementation of the power electronic circuit is placed in the EV charger station.
