Abstract
According to an implementation, a resonant converter for short-circuit protection includes an oscillator, a short-circuit detector configured to detect a short-circuit condition in a component of the resonant converter, and a pulse width modulation (PWM) controller configured to control the oscillator in a PWM mode before short-circuit protection is triggered. The oscillator, when in the PWM mode, is configured to generate a first clock signal for driving a first power switch and a second clock signal for driving a second power switch.
