Title: Switching power circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 2000-10-24
Abstract: PROBLEM TO BE SOLVED: To dispense with magnetic shielding with a copper plate against with respect to an insulating converter transformer or a high-voltage generating transformer. SOLUTION: In a switching power circuit having a complex-resonant converter circuit, converter operation is set, so as to be synchronized with a horizontal synchronizing signal used in a cathode-ray tube display, thereby eliminating generation of power beats caused by interference of leakage flux of the converter transformer or the high-voltage generating transformer with the horizontal synchronizing signal. It is thus possible to eliminate use of a shielding member for shielding the leakage flux in each of the transformers.
