Abstract
There is disclosed a power conversion circuit including self synchronous rectifiers and a rapid shutdown section. When power is removed from the power conversion circuit, the rapid shutdown section prevents self oscillation of the self synchronous rectifiers. As a result, power is not drawn from the output and dissipated in the power conversion circuit.
