This project proposed a silicon carbide (SiC)-based (IGBT/SiC-diode) cascade quasi-impedance-source inverter (qZSI) for a utility-scale PV power with a transformative holistic approach – from developing low-cost SiC wafers, high voltage/power SiC devices, to LC filter-/transformer-less low-cost high-reliability inverter topology. The RD&D (Reseach, Development, and Demonstration) project will provide the following advances: LC filter-/transformer-less qZS cascade multilevel inverter for...

1-MW PV Power RD&D Using SiC based qZS Cascade Multilevel In

This project is aimed at the development of advanced discrete time control algorithm based on the model predictive control (MPC) approach for various power electronics converter topologies and variable speed electric drives. The main characteristic of the MPC is to use the controlled system model to predict its future behavior and to use predefined cost function to optimize the control performance. The MPC performs the control action in a single loop and do not require any modulator contrary to...
