High efficiency Silicon carbide DC-AC inverter for EV-charging Flywheel system

The paper deals with the design and experimental validation of a high efficiency DC-AC inverter with new technology Silicon carbide-based MOSFETs transistors used for the supply of a flywheel energy storage system dedicated to electric vehicles charging. High efficiency in reversible mode, compactness and thermal enhancement are the target objectives for the converter prototype. High frequency switching and PWM tests, design aspects for the DC busbar and first stage of hardware realization are presented and discussed.
