摘要： The AC power generated by AC utility has been successfully transferred from AC-to-DC by means of an AC-to-DC converting circuit. This disclosure provides an AC-to-DC converting circuit applicable to a power-charging module, and the AC-to-DC converting circuit comprises two parts such as a first stage being a 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 being an AC-to-DC converter comprising a single-phase transformer and a full-bridge rectifier, where the inverter in the first stage is switched at high frequencies so as to reduce the size 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 power-charging module, reduce the number of current measuring elements and the cost thereof.
