    • A control unit performs the first-third controls. The first control controls a group of switch elements so that a step-up voltage is supplied to a voltage output terminal by a pumping action of a step-up voltage accumulating capacity element by applying the reference power source voltage to the reference power source voltage accumulating capacity element in an inverse direction, after execution of an electric charge accumulating action with the reference power source voltage in the reference power source voltage accumulating capacity element. The second control controls the group of switching elements so as to provide a dead-time period, during which the reference power source and the reference power source voltage accumulating element are disconnected, between a period of the electric charge accumulating action and a period of the pumping action and between the period of pumping action and the period of electric charge accumulating action. The third control achieves such a control in the first and second step-up circuit units alternately and cyclically that the electric charge accumulating action or the pumping action in one of the first and second step-up circuit units is carried out, when the other is in the dead-time period.
    • 控制单元执行第三至第三控制。 第一控制器控制一组开关元件,使得通过将参考电源电压施加到参考电源电压累加的升压电压累积电容元件的泵送作用,将升压电压提供给电压输出端子 在参考电源电压累积电容元件中执行与参考电源电压的电荷积累动作之后,反向的电容元件。 第二控制器控制开关元件组,以便在电荷累积动作的周期与电荷累积动作的期间之间,提供参考电源和基准电源电压蓄积元件断开的死区时间 泵送动作之间和泵送动作期间与电荷累积动作期间。 第三控制在第一和第二升压电路单元中交替地和循环地实现这样的控制,即当第一和第二升压电路单元中的另一个是第一和第二升压电路单元中的一个时,进行电荷累积动作或泵送动作 在死亡时期。
