An energy delivery system comprises a power supply configured to generate a pulsed output voltage and a pulsed output current, and an over-energy protection (OEP) circuit coupled to the power supply. The OEP circuit senses the output current of the power supply and generates a sensed current signal, generates a charge-delivered signal from the sensed current signal that is representative of the charge delivered by the power supply over a time interval, and generates a fault signal that disables the power supply if the charge-delivered signal exceeds a threshold.

Over-energy protection for a power supply

A gate driver circuit comprises an auxiliary winding, a voltage summer, an auxiliary voltage bus, a gate driver integrated circuit (IC), and a controller. The auxiliary winding is positioned adjacently to the inductor and configured to inductively couple with the inductor. The voltage summer comprises a pair of diodes coupled to the auxiliary winding and a pair of capacitors coupled to the pair of diodes. The auxiliary voltage bus is configured to receive a summed voltage from the voltage summer based on a sum of voltages stored in the pair of capacitors. The gate driver IC is configured to receive a voltage from a positive rail of the auxiliary voltage bus and to output a gate control signal to control a switching device based on the received voltage and based on a pulse signal generated by the controller.
