Abstract
A power supply circuit employed in various types of electronic appliances, telecommunications equipment, and the like, is provided for generating a voltage pulse by resonance effect of a primary side of a transformer, and outputting the voltage pulse from a secondary side after raising a voltage thereof. The power supply suppresses fluctuations of electric current, and prevents noise from being propagated through a device powered by the supply. A control circuit actuates a second switching element into a non-conducting state while a first switching element is in a conducting state. The power supply switches the second switching element into a conducting state when voltage of a primary coil is greater than voltage of a driving power supply after an electric current flows in a first diode while the first switching element is in a non-conducting state.
