Common-source inductance (CSI) is proven to be detrimental for high-speed switching. It can significantly slow down switching speed and increase switching losses. Recent research also demonstrated a self-turn- on phenomenon during the device turn- of

Wide-bandgap devices like silicon-carbide (SiC) MOSFETs and gallium nitride (GaN) HEMTs feature fast switching speed, low switching losses, and higher operating temperatures. However, with the high di/dt and dv/dt slew rates, even small stray inducta

Voltage source converters (VSCs) with $LCL$ filters are attractive in grid-connected applications because they greatly reduce the pollution of the utility voltage due to switching harmonics. However, $LCL$ networks have very low impedance at frequenc
