Abstract
A controller for performing a zero voltage switching using a resonance mode converter, and an electronic ballast adopting the same, includes a power controller, a shutdown protection circuit and a brownout circuit, and performs a switching when voltage of a switching element is zero, thereby preventing excessive power consumption, enhancing efficiency and decreasing noise.
