ABSTRACT:
A DC/DC converter for producing a plurality of output voltages, comprising a transformer having a primary coil and a plurality of secondary coils; a switching circuit adapted to turn ON and OFF the supply of input DC voltage to the primary coil; rectifying and smoothing circuits for rectifying and smoothing the AC voltages obtained in the secondary coils; a circuit means connected in series with the rectifying and smoothing circuits to obtain the sum of the output voltages from the respective rectifying and smoothing circuits; and a control circuit adapted to receive the lowest DC output voltage from the rectifying and smoothing circuits and to control the ON - OFF operation of the switching circuit so that the lowest voltage is maintained at a constant level, and wherein the DC voltages from the respective rectifying and smoothing circuits are obtained by making use of one of the output terminals of the lowest DC voltage as a common terminal.
