    • A charge pump device is coupled to first and second input terminals receiving an AC signal and comprises an electric switch set and two voltage boost circuits. The electric switch set is coupled to the first and second input terminals and a ground terminal and switches the conduction status thereof according to the AC signal. The two voltage boost circuits are interconnected and coupled to the first and second input terminals and the electric switch set. The boost circuits receive the AC signal according to the conduction status, respectively boost voltage in positive and negative semi-periods of the AC signal, and alternatively output a voltage at least two times the peak voltage of the AC signal, to a load. The present invention not only boosts voltage by several folds within a cycle but also outputs voltage by dual phases to reduce ripple of output voltage.
    • 电荷泵装置耦合到接收AC信号的第一和第二输入端,并且包括电开关组和两个升压电路。 电开关组耦合到第一和第二输入端子和接地端子,并根据AC信号切换其导通状态。 两个升压电路互连并耦合到第一和第二输入端子和电开关组。 升压电路根据导通状态接收交流信号,分别在交流信号的正半周期和负半周期内升压电压,或者将至少两倍于交流信号的峰值电压的电压输出到负载。 本发明不仅在一个周期内提高了几倍的电压,而且通过双相输出电压,以减少输出电压的纹波。
