Abstract
A power conversion driving circuit is provided. The power conversion drive circuit includes a converting circuit, a control circuit and a load circuit. The converting circuit is coupled to an input voltage. The control circuit is coupled to the converting circuit for controlling the converting circuit to convert the input voltage to an output voltage. The load circuit includes a load detecting unit and a load. The load is coupled to the output voltage, and the load detecting unit is coupled to a detecting voltage source. The load detecting unit generates a load detecting signal to re-start the control circuit when the load circuit is inserted into the power conversion driving circuit.
