HALF-BRIDGE TYPE DC-DC CONVERTER

摘要

PROBLEM TO BE SOLVED: To provide a DC power supply device capable of achieving reductions in cost and size and converting a DC power supply to a predetermined voltage at a constantly high conversion efficiency without depending upon fluctuations in an input voltage.;SOLUTION: In the DC power supply device having a wide input voltage range, a voltage applied to a transformer depends on an input voltage range. In a circuit consisted of a switching element and a capacitor, however, the switching element and the capacitor are disposed so that an input voltage is partially pressed to suppress the voltage applied to the transformer within a fixed range.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
