Abstract

PURPOSE:To provide an appropriate solenoid driving circuit without using a transformer, by using n-stage voltage doubler circuits and optimizing the value n depending on a load. CONSTITUTION:When the potential on a point 1 is higher than that on another point 2 for a first half cycle, a charging current flows through a diode S1 and the voltage across a capacitor Ca becomes equal to the peak value of an AC voltage. Since the potential on the point 2 is higher than that on the other 1 for the next half cycle, another capacitor Cb is charged by a voltage equal to the sum of the AC voltage and the voltage across the former capacitor Ca. Therefore, the voltage across the capacitor Cb becomes double the peak value of the AC voltage if the capacitor Ca is not discharged during the latter cycle. N stages of such half-wave voltage doubler circuits are provided so that an n-time voltage multiplication circuit is constituted. A solenoid is used as a load. In the initial period of that case, a considerably high voltage can be applied. The capacity of capacitors except for the final-stage one is set low in order to reduce a holding current after attraction by the solenoid. The value n is experimentally determined depending on the load.
