Abstract
PURPOSE: To obtain the circuit whose output voltage can be turned off easily at a high speed and further adjusted under external control with the simple constitution of an FET photocoupler, control voltage generating circuit, etc.
CONSTITUTION: The output of oscillator G oscillating at a prescribed frequency is inputted to one terminal of the secondary side of FET photocoupler Q via semiconductor switch S, and the output from the other terminal of photocoupler Q to the input side of power amplifier A1. The signal amplified by this amplifier A1 is boosted by transformer T and applied to a body to be detected. To the primary side of photocoupler Q, control voltage generating circuit B and differential amplifier A2 are connected; the secondary side voltage of transformer T is applied to one input of amplifier A2 via voltage-dividing resistance R and rectifying circuit AD, and the voltage adjusted by output-voltage-adjusting variable resistance VR to the other input. Then, the primary side voltage of photocoupler Q is increased slowly and the output of amplifier A1 is also increased slowly for external control over switch S to turn off the output at a high speed, so that the output voltage can further be adjusted by resistance VR.
