    Abstract:

    This paper seeks to explore the benefits brought by PCB-embedded Rogowski switch-current sensors integrated on the gate driver of a 1.2 kV, 300 A SiC MOSFET half-bridge module. They collect two MOSFET switch currents in a manner of high magnitude, high bandwidth, and solid signal isolation. Apart from high bandwidth switch-current signals...More
