Abstract
PURPOSE: To eliminate the impulse noise by connecting the serial circuit of the capacitor and the resistance in parallel to the coil of the serial resonance circuit.
CONSTITUTION: Coil L and capacitor C forming a resonance circuit are connected in series to the joint of two transistor switches QP and QN. Furthermore, capacitor C' and resistance R' connected in series each other is connected in parallel to the coil. When the voltage of ±E is applied to the resonance circuit alternately via switches QP and QN, the sine wave current flows to the resonance circuit. And the impulsive voltage of the output voltage of the coil driving circuit is attenuated so much so that it can be ignored in terms of the practical use by the serial function of capacitor C' and resistance R' which are connected in parallel to coil L. As a result, the clamping circuit for voltage protection of the switch transistor of the driving circuit can be omitted.
