    • A voltage step-up circuit, or booster circuit, wherein in response to a first signal a first switching element is enabled to charge a first capacitor with an input voltage while a second switching element is disabled, and in response to a second signal the second switching element is enabled to charge with the input voltage a second capacitor connected in series to the first capacitor while the first switching element is disabled. The sum of the voltages appearing across the first and second capacitors is derived as an output voltage. The "ON" and "OFF" times of the first and second signals may be varied, and the ratio between the "ON" time of the first signal to the "ON" time of the second signal may also be varied. The number of switching elements and capacitors may be increased as needed.
    • 一种升压电路或升压电路,其中响应于第一信号,第一开关元件能够在禁用第二开关元件的同时对具有输入电压的第一电容器充电,并且响应于第二信号,第二开关元件 开关元件能够使输入电压对第一电容器串联连接的第二电容器进行充电,而第一开关元件被禁用。 导出出现在第一和第二电容器两端的电压之和被导出为输出电压。 可以改变第一和第二信号的“ON”和“OFF”时间,并且也可以改变第一信号的“ON”时间与第二信号的“ON”时间之间的比率。 可以根据需要增加开关元件和电容器的数量。
