The AC power source generated from municipal factory, is already very popular in regard being transferred from AC to DC by means of AC to DC converter. The present invention relates to a AC to DC converter applicable to a power charge module, and the circuit comprises two parts such as a first stage, low-frequency AC to high-frequency AC converter comprising an input full-bridge rectifier, a full-bridge inverter, and an immittance conversion circuit, and, a second stage, AC to DC converter, comprising a single-phase transformer and a full-bridge rectifier, where the inverter in the first stage is switched in high frequency so as to reduce the volume of the transformer in the second stage. Additionally, the immittance conversion circuit is further characterized in voltage to current conversion so as to simplify the control mechanism of the charge module so as to reduce the current measuring elements and the cost thereof.
