Title: Switching power supply
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 2003-12-04
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the number of circuit components and the cost for manufacturing a circuit of a wide-range switching power supply circuit, where the power factor is improved by a voltage-feedback system.  <P>SOLUTION: An inductance value forming a primary series resonance circuit is varied, by making a current level being fed to the control winding Nc of a voltage feedback transformer VFT variable, depending on the commercial AC power supply level, thereby making the inductance of a primary winding N4 variable. A required control range of stabilization operation through switching frequency control of an AC 100V system and an AC 200V system is confined within the maximum control range of switching frequency, thus realizing a wide range switching power supply circuit through stabilization operation. Since a conventional arrangement for switching the rectification operation is not required for realizing a wide-range switching power supply circuit, design for the rectifying/smoothing circuit and the power factor improving circuit is not limited. Consequently, the number of components is decreased, breakdown voltage of elements is lowered, and the circuit cost can be reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
