<p>PURPOSE: A switching power supply device using a parallel transformer is provided to implement thin shaping by optimizing the arrangement of two transformers and a resonance element. CONSTITUTION: Two switches(Q1,Q2) are connected to an input power source in series. A resonance capacitor(CR) is connected to the central node of the switches. Two resonance inductors are connected to the capacitor in parallel. Two transformers(T1,T2) are individually connected to the two resonance inductors in series. A full-wave rectifier uses two diodes in center tap output.</p> |
