Abstract

PURPOSE:To simplify circuit constitution without using a pulse transformer, etc., by composing a TRIAC driver circuit of a single-power supply control commonminus- pole type of general elements such as a transistor, resistance and capacitor. CONSTITUTION:Electrode T1 of TRIAC S connected to alternating power supply E in series to load L is connected to the earth side of driving transistor circuit A and the minus side of direct-current power supply B, and the output side of this transistor circuit A is connected to gate G of TRIAC S via capacitor C and resistance R, thereby constituting the TRIAC driver circuit. In this constitution, a common-minus-pole type TRIAC driver circuit is composed of general elements such as TrQ, resistance R and capacitor C and direct-current power supply B is used only for charging capacitor C, so that the circuit constitution will be simplified without a pulse transformer, etc.
