Silicon Carbide Driver Using High Voltage Capacitors for Isolation and Signal Transmission

Abstract: a gate driver circuit to receive an input drive signal and output an output drive signal is provided. the gate driver circuit may include a first capacitor having first and second terminals, a second capacitor having first and second terminals, a first set of switches to selectively couple the first terminals of the first and second capacitors to the input drive signal and a power supply voltage, a second set of switches to selectively couple the second terminals of the first and second capacitors to a reference voltage and a high impedance node, and a comparator having a first terminal coupled to the reference voltage and a second terminal coupled to the high impedance node. the comparator may output the output drive signal based on a comparison of the reference voltage and a voltage at the high impedance node.
