Abstract: A power source circuit and an application thereof are provided. A multi-phase AC power source is generated by means of a given AC power source by using an electromagnetic induction relationship between electrically conductive winding coils on a magnetically conductive iron core, routed through a multi-phase bridge rectifier circuit, and then directly used as a DC voltage source having a very small ripple factor to output DC voltage and current without capacitor filtering, thereby high-order harmonics caused by capacitor filtering are eliminated radically. In addition, the current in the multi-phase bridge rectifier circuit that is inputted from a power grid is a sine wave or a step wave that is very close to a sine wave, so that the high-order harmonics generated on an AC side is minimized without power factor correction.
