Abstract

PURPOSE:To start a load softly, by preventing the rush current due to turning- on of a power supply switch in a circuit which discharges instantaneously a capacitor when the load such as a transformer, a motor, a vibrator, and an illumination lamp is controlled. CONSTITUTION:When a power supply switch SW is turned on, an earth circuit consisting of a terminal 15 of a rectifying circuit 10, a light emitting diode 13 of a photocoupler HP1, and a resistance R2 is completed, and a phototransistor TR 14 of the coupler HP1 is conductive, and a point B1 of a TR Tr1 is set to a +potential, and an emitter and a collector C of the TR Tr1 are nonconductive. Simultaneously, a capacitor C3 is discharged gradually through a diode D6 to change the potential at a point B2 to a -potential gradually. The soft start time is made variable to complete an earth circuit consisting of a TR Tr2, a resistance R4, a variable resistance VR2, and a capacitor C4 and an earth circuit consisting of the variable resistance VR2, the TR Tr2, and a pulse transformer PT.
