Abstract

PURPOSE:To prevent the generation of noise, by using a power transistor and picking up an AC output continuously. CONSTITUTION:An AC voltage is applied between input terminals 1 and 2, and a voltage corresponding to a variable resistor VR1 is generated between output terminals 3 and 4. When a positive voltage is applied to the terminal 1, a current flows to the terminal 2 through a resistor R2, diode D3, variable resistor VR1 and a diode D6. In this case, the conduction of a drive transistor Q3 and a power transistor Q1 is controlled with the variable resistor VR1 and an output voltage is generated across the resistor R1. When the terminal 2 is applied with a positive voltage, control is made with a drive transistor Q4 and a power transistor Q2.
