<p>PURPOSE:To simply improve voltage regulation by mutually shifting resonance frequency by a primary winding part and resonance capacitors. CONSTITUTION:When resonance frequency by a primary winding part PC and resonance capacitors CP1 and CP2 is mutually shifted, a synthetic primary pulse waveform is approximated to a rectangular wave, whereby a peak current Ip flowing through a secondary winding becomes small. That is, voltage regulation is made improved by making the peak current Ip small for making a forward voltage drop Vr due to a diode, a voltage drop Vr due to winding resistance and a voltage drop Vx due to leakage reactance small. Thereby, addition of a separate circuit is not necessary while causing no rise in cost.</p> |
