Abstract
An AC to DC converter circuit includes a main circuit including a first circuit and a second circuit connected to an AC power supply in parallel to each other, the first circuit including diodes and a switching device, the second circuit including diodes and a switching device. The switching devices are controlled to be ON and OFF corresponding to the input voltage polarity discriminated with an input voltage polarity discriminator such that two DC outputs are obtained from one AC power supply. The AC to DC converter circuit reduces the semiconductor devices, through which a current flows, facilitates reducing the losses caused therein, improving the conversion efficiency thereof, and reducing the size, weight and manufacturing costs of the cooling means thereof.
