High power wide bandgap cascode switching circuits
… JFET cascodes benefit from improved gate drive, reverse conduction and switching characteristics. SiC MOSFETs are shown to be better suited to efficient high temperature operation, while SiC JFETs are more appropriate for high current applications. Cascode switching losses are shown to be reduced …

Third Quadrant Operation of 1.2-10 kV SiC Power MOSFETs
The third quadrant (3rd-quad) conduction (or reverse conduction) of power transistors is critical for synchronous power converters. For power metal-oxide-semiconductor field-effect-transistors (MOSFETs), there are two current paths in the 3rd-quad conduction, namely the MOS channel path and the …

Highly Efficient Gan-Based Single-Phase Transformer-Less Pv Grid-Tied Inverter
… this dissertation studies GaN power devices - reverse conduction capability to provide the proposed inverter with reactive power control. Existing PWM techniques cannot provide a freewheeling path in the negative power region to generate reactive power in a single-phase transformer-less …
