並列制御式チョッパー回路。 −゛(1) In a chopper circuit having an on/off control port for the main transistor inserted in parallel with the load, and a main circuit that rectifies and smoothes the chopping output and supplies the chopped output to the load, the base current is drawn to the base circuit of the main transistor. A series circuit of a resistor and a capacitor is provided between the base of the base current drawing transistor and the main circuit, and the base current drawing transistor is temporarily activated by the charging current to the capacitor when the main transistor is off. Parallel control type chopper circuit that conducts electrically. −゛
