Abstract
In one or more embodiments, one or more systems, methods, and/or processes may: receiving, by a first circuit of an inductor-inductor-capacitor (LLC) converter, a pulse width modulation (PWM) signal to control a gate of a metal-oxide-semiconductor field-effect transistor (MOSFET) of a plurality of metal-oxide-semiconductor field-effect transistors (MOSFETs) of the LLC converter; provide, by the first circuit, current to a transformer based at least on amplifications of the PWM by at least one of the plurality of power MOSFETs; determine, by the second circuit, if a voltage value associated with a drain of the power MOSFET is above a threshold voltage value; if so, suppress, by the second circuit, the PWM signal to the gate of the power MOSFET; and if not, permit, by the second circuit, the PWM signal to the gate of the power MOSFET.
