The input PWM switching voltage stabilized system for the purpose of compactness and stability output of low voltages and high current is a switching regulator of the directly switching system. According to the developed system, the commercial power voltage is converted into 400Hz pulses by the direct switching circuit, then, it is transformed to low voltages by a transformer, rectified and filtered to obtain DC voltages. At the same time, output DC voltages are automatically by controlling the conduction time of converter GCS (Gate Controlled Switch). This system has the following features. This reduces the rectifier and the smoothing circuit required to convert the commercial power voltage to DC voltages. As the result, it can be simplified. Since this transformer is replaced with 400Hz one, size and weight of the unit is minimized. This power supply uses a three-phase power supply which has advantages to provide a power.
