ことを特徴とするスイツチング制御型電源回路。 In a power supply circuit that stabilizes the output voltage by controlling the on and off periods of a separately excited switching circuit connected to the input winding of the transformer by a control circuit that detects the output voltage from the transformer, when the power is turned on. By applying the DC input to the control circuit,
a switch for operating the switching circuit; a delay circuit that operates after a predetermined time has elapsed after the power is turned on; and the operation of the delay circuit opens the switch and connects the primary and secondary sides of the transformer. A switching control type power supply circuit characterized by being provided with a switch control circuit for setting an insulating state.
