PROTECTION CIRCUIT, RESONANT CONVERTER INCLUDING THE PROTECTION CIRCUIT, AND PROTECTING METHOD OF THE RESONANT CONVERTER

摘要

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.
