Abstract

PURPOSE:To attain a small-sized device not requiring an excessive DC converting means by a method wherein a two-way control rectifying element controlled by a DC output voltage is used for stabilizing the DC output voltage. CONSTITUTION:In the control circuit CLT2, a comparator COM is fed with an output from a triangular wave oscillator OSC and an output voltage V0, and the output of the comparator turns gate circuits G1, G2 ON or OFF alternately directly and through a flip-flop FF to cause interrupted voltages V1, V2 to be fed as outputs. The interrupted voltage V1 is phase-inverted by a drive transformer DT1 to be applied to the 2-way transistor and the interrupted voltage V2 in the notinverted phase. An interrupted current I2 flows in the primary winding of a transformer, being controlled by the interrupted voltage V2 and by the interrupted voltage V1 in a negative half period. Thereby, the interrupted voltages fed to the secondary winding are commutation-flattened to feed the DC voltage V0. The fluctuation of the voltage V0 changes an impulse ratio of the interrupted voltages V1, V2 and as a result, the output voltage V0 is stabilized.
