Abstract: An AC-DC converting apparatus and operating method are provided. The AC-DC converting apparatus includes a transformer, a first energy storage unit, a first output switch, a second energy storage unit, a second output switch and a secondary-side control module. The transformer includes a primary-side winding and a secondary-side winding. The first output switch is coupled between the secondary-side winding and the first energy storage unit. The second output switch is coupled between the secondary-side winding and the second energy storage unit. The secondary-side control module monitors the first energy storage unit and the second energy storage unit, and decides time length of a conduction period of the first output switch and the second output switch according to the monitoring result.
