Abstract
A capacitor can be charged at a high speed by applying a direct current voltage intermittently to the capacitor. The direct current voltage is intermittently applied to the capacitor such that a preceding applied voltage E1 is larger than a succeeding applied voltage E2. Thus, the charging is swiftly progresses and the capacitor can be charged at a higher speed than when the voltage is applied continuously.
Claims5
A method of charging a capacitor by intermittently applying a direct current voltage to the capacitor, comprising the steps of:
- initially applying a voltage E1 to the capacitor;
- and then applying a voltage E2 to the capacitor, wherein E2 is smaller than E1.
