チヨーク・コンバータ電源装置。[Claims for Utility Model Registration] DC voltage supply means; a converter transformer having an input winding, an output winding, and a drive winding; an input DC voltage from the DC voltage supply means to a collector via the input winding; a switching transistor whose emitter is connected to a common potential point and whose base is applied with a voltage induced in the drive winding; the DC voltage supply means, the input winding, and the collector of the switching transistor; The first one is placed somewhere in the path and reduces the voltage generated in the drive winding in response to an increase in the collector current.
a second resistor disposed between the DC voltage supply means and the base of the switching transistor; and a starting current supplied from the second resistor to the base of the switching transistor at startup. A ringing device characterized by comprising a slow startup circuit that bypasses the ON operation to delay the ON operation and gradually accelerates the ON operation as the startup current increases.
Chiyoke converter power supply.
