Patent JP-2002305878-A (JP)
Title: Switching power supply
Inventor: YASUMURA MASAYUKI
IPC: H02M3/338
Filed: 2001-04-03
Abstract: PROBLEM TO BE SOLVED: To ensure the breakdown strength of a switching element upon the occurrence of shot circuit of a load by reducing the margin of design. SOLUTION: A self-excited voltage resonance converter is employed on the primary side of a composite resonance converter and a voltage subjected to variable control depending on the level of a secondary-side DC output voltage is applied to the gate electrode of an MOS-FET for the purpose of constant voltage control. The capacitance of a self-excited oscillation circuit comprising a series circuit of the drive winding of a drive transformer and a series resonance capacitor is varied by the conducting state of the MOS-FET and a switching frequency is controlled variably. Consequently, a switching element is subjected to switching control by a composite control system where an conduction angle and the switching frequency are varied simultaneously.  Under a short circuit state of the load or at the time of power input, the switching frequency is controlled to have a maximum value within a control range so that an undue voltage is not applied to the switching element.
