ABSTRACT:
A power supply device capable of supplying high DC voltages of positive and negative polarities has a transformer having a primary coil and two secondary coils. A DC current supplied to the primary coil is switched to generate voltages in the secondary coils. These voltages are rectified and smoothed in mutually opposite polarities, and the output voltages are obtained by summing the rectified and smoothed voltages.
