Abstract
PURPOSE:To enable to obtain the output voltage which is stable regardless of the input voltage and load, by providing a Triac, trigger circuit driving Triac, time constant circuit, reference control voltage generating circuit, feedback circuit and breeder resistances. CONSTITUTION:The input voltage from the terminal IN is applied to one end of the bidirectional switch SBS of the trigger circuit via the filter circuit 1, reference control voltage generating circuit 2, and time constant circuit 3, and a voltage dividing the input voltage with resistances R4, R5 is applied to another end of SBS with the feedback circuit 6. The output of the circuit 4 is inputted to the gate terminal of the Triac T via the capacitor C4. A voltage is applied to SBS according to the amplitude of the input voltage, and the conduction angle of the Triac T is greater when the input voltage is lower and smaller when the input voltage is higher. Control is made so that the variance of the input voltage can be cancelled. A fixed effective voltage is supplied to the output terminal OUT. Further, abnormally high voltage at no load can be prevented with the breeder resistance R7 connected in parallel with the terminal OUT.
