Title:
FLYBACK TRANSFORMER
Document Type and Number:
Japanese Patent JP3116586
Kind Code:
B2
Abstract:
PURPOSE: To simply configure an inexpensive and small sized flyback transformer by eliminating a high voltage capacitor from a 2-fold voltage rectifier circuit.
CONSTITUTION: Secondary windings of a flyback transformer are consisted of plural windings 13, 14, 15 wound in alignment in a same direction, stray capacitance 18, 19 between the secondary windings are used for high voltage capacitors of a 2-fold voltage rectifier circuit to form the 2-fold voltage rectifier circuit dispensing with any high voltage capacitor. Thus, the high voltage capacitor is eliminated from a secondary side high voltage 2-fold voltage rectifier circuit and the inexpensive 2-fold voltage rectifier circuit is simply configured.
