The picture shows the touch type voltage regulator,which can adjust the photoconductive resistance mainly by changing the brightness of LED,and then adjust the conduction degree of the bidirectional thyristor through triggering the diode trigger circuit, and ultimately achieve the purpose of the voltage regulation.The circuit is shown as picture.It consists of bidirectional thyristor trigger circuit, LED brightness adjustment circuit as well as regulating impulse generation and control circuit.
