Abstract
A power conversion apparatus is provided. A bargaining circuit adjusts a feedback voltage output by an optocoupler to make a control circuit reduce an output voltage of a transformer circuit, and turns off the optocoupler when the output voltage of the transformer circuit is lower than a first setting voltage to increase the feedback voltage. The control circuit executes a limited power operation when the output voltage of the transformer circuit is lower than the first setting voltage and the feedback voltage is higher than a second setting voltage.
