Title: Switching power circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 2002-07-05
Abstract: <P>PROBLEM TO BE SOLVED: To maintain favorable power conversion efficiency even under the condition that load power Po is not less than 125W and expand a range of regulation.  <P>SOLUTION: A composite resonance converter is formed by combining a current resonance converter and a primary-side partial voltage resonance circuit. By winding tertiary winding on the primary side, the composite resonance converter is so constituted that direct-current voltage obtained from alternating voltage produced in the tertiary winding is superposed on rectifying and smoothing voltage. The current resonance converter is operated by inputting direct-current input voltage obtained by superposing the direct-current voltage on the rectifying and smoothing voltage. The numbers of turns for the primary winding and the tertiary winding are set to predetermined values so that required or higher inductance is obtained. With this arrangement, the range of fluctuation in direct-current input voltage is reduced. Further, as the result of the inductance of an insulating converter transformer being set to a required value or higher, the level of a current passed through the primary winding and switching elements is reduced.  <P>COPYRIGHT: (C)2004,JPO
