Abstract: A system and method for capturing current information for a power converter is disclosed. The current monitoring system includes a control system operably connected to a circuit having a plurality of semiconductor switches that are controllable to convert an input power to an output power having a desired voltage and current. The control system includes a PWM signal generator to generate switching signals that control switching of the switches, gate drivers to facilitate switching of the switches, and desaturation circuits to provide overcurrent protection to the switches. The control system further includes a processor that receives voltage data from the desaturation circuits regarding a measured voltage across each of the switches, determines a current through each of the switches based on the voltage across each respective switch, and calculates an input current to the circuit or an output current of the circuit based on the determined currents through the switches.
