Document Type and Number:
Japanese Patent JP5683241
Kind Code:
B2
Abstract:
A switching power supply apparatus includes a voltage holding unit which holds voltage generated in an auxiliary winding of a transformer, and a voltage detecting unit which detects voltage applied to the first switching unit. When the first switching unit operates such that voltage generated in a secondary winding of the transformer may be low, voltage is supplied from the voltage holding unit to the first switching unit in accordance with the voltage detected by the voltage detecting unit to thus turn on the first switching unit.
