Title:
STABILIZED POWER SUPPLY
Document Type and Number:
Japanese Patent JPS58106621
Kind Code:
A
Abstract:
PURPOSE:To attain power supply stabilization with useless radiation and switching loss by outputting a pulse output from a converter circuit via a stabilizing circuit, using a small-sized transformer. CONSTITUTION:The converter circuit 20 forms a resonance circuit 21 consisting of a coil 22 and a capacitor 23. The stabilizing circuit 30 forms a resonance circuit 31 comprising a coil 32 and a capacitor 33. The pulse output from the circuit 20 is applied to the output transformer 60 via the circuit 30, a current flows to the secondary winding 61 of the transformer 60 to conduct a rectifying diode of a rectifier circuit 50. In this case, the magnetic flux by the current flowing to the primary and the secondary windings of the transformer 60 is cancelled with each other to make the core of the transformer 60 hardly saturated. Thus, a large current is loaded with the small-sized transformer 60.
