Abstract

PURPOSE:To stabilize the output voltage of a DC-DC converter by connecting a resonance circuit to a switching element to make the current zero at on-off of the element. CONSTITUTION:Switching elements 3, 4 and coils 15, 16 for resonance are connected in series between both terminals of an input DC power supplies 1, 2. Diodes 5, 6 are connected respectively in parallel to the switching elements 3, 4 and a condensor 7 for resonance and a primary winding 10 of a transformer 9 are connected in series between an intermediate point m of the DC power supplies 1, 2 and an intermediate point n of the coils 15, 16 for resonance. A secondary winding 11 of the transformer is connected from a recitifer circuit 12 to a load 14 while it is inputted from a differential amplifier 20 to a comparator 21 together with an output of a saw-tooth wave generating circuit 19. Hereby, the current of the switching elements 3, 4 at on-off becomes zero, and the stabilization is effected without influencing on the output voltage.
