Abstract

PURPOSE:To reduce the loss of a DC conversion circuit by using a capacitor, a diode, a resistor, etc., as low-cost parts in place of a transformer. CONSTITUTION:A switching power circuit is constituted in such a manner that an input DC power 1-1, an inductance 1-2 and a transistor(Tr) 1-3 are connected in series, and the Tr1-3 is turned ON-OFF by a base driver circuit 1-4. A capacitor 1-6 is connected to a collector for the Tr1-3, and output voltage is extracted from a capacitor 1-11 through first-second diodes 1-7-8, etc., from other terminals. Accordingly, the output loss of a power supply can be reduced by using the capacitors, the diodes, etc., in place of a winding for an expensive transformer.
