摘 要：
PROBLEM TO BE SOLVED: To inexpensively provide a sensor drive circuit for stabilizing a voltage to be
supplied to a sensor circuit while reducing power loss.;SOLUTION: A transistor Q1 to be energized in a direction of supplying a positive voltage to a bridge circuit B is arranged between the bridge circuit B and an AC voltage source which is not shown. A diode bridge 12 is arranged between the bridge circuit B and the AC voltage source which is not shown, and fully rectifies an AC voltage supplied to the bridge circuit B. A comparison circuit 13 controls the transistor Q1 to prevent the value of the AC voltage supplied to the bridge circuit B from exceeding a voltage Vth by comparing the AC voltage supplied to the bridge circuit B with the voltage Vth.;COPYRIGHT:
