Abstract: A power converter includes an output unit, a first transformer, a switch unit, and a processing unit. The first transformer includes a primary winding and a secondary winding. The primary winding is coupled between an input voltage and a first node. The switch unit is coupled between the first node and a second node. The processing unit is coupled between the input voltage and the first node. When the switch unit is in an OFF state, the processing unit is used to receive a first sensing voltage and store a sensing power of the first sensing voltage through a first path, isolate the first sensing voltage from feeding in through a second path different from the first path simultaneously, and then release the stored sensing power through the second path. The first sensing voltage is generated as the switch unit switches from an ON state to the OFF state.
