Abstract: PURPOSE:To generate a stable AC bias voltage by generating the development AC bias voltage by automatically adjusting the gain of an amplifier so that a DC voltage by rectification is constant, by amplifying a sine-wave oscillation output voltage. CONSTITUTION:A sine-wave voltage outputted from one of sine-wave oscillating circuits 9a and 9b differing in frequency is amplified by an amplifier 10 and then boosted by a boosting transformer 11 to generate a sine-wave AC bias voltage.

A set voltage is retained by capacitors 23a, 23b to become an applied voltage to said exciting coil. At the same time that said transistor 20a changes to the OFF state, an electric signal is inputted from a terminal 19b so that a transistor 20d is turned ON and power is applied to an exciting coil D. Magnetic energy stored in the exciting coil C charges said capacitor 23b by the electromotive force acting in the direction of the arrow B and is also stored as magnetic energy for the exciting coil D, and both energies are discharged via diode 22a. As said discharge current disappears within the section of 180 degrees so that no antitorque is generated and the efficiency of an apparatus can be enhanced.
