PURPOSE:To obtain the prescribed DC power source voltage from the constant DC power source voltage by small size and inexpensive means by switching the charging of the first charger and the charging of the second charger at the prescribed time. CONSTITUTION:When a switch operation element 2 is turned ON, a booster capacitor C1 is charged by an input DC power source voltage E. Then, an output capacitor C2 is charged by the voltage E. Further, the initial charging voltage of the booster capacitor C1 is applied to the capacitor C2. When this operation is repeated, the terminal voltage of the capacitor C2 finally becomes twice of the input DC power source voltage. |
