Abstract:
The present invention relates to a protection circuit, a resonance converter having the same, and a protection method thereof.A resonance converter having high-side and low-side switches senses a current flowing through the low-side switch and determines a zero voltage switching failure by using a width of a current flowing to a negative direction of the low-side switch.
