This paper introduces a lithium battery-powered portable by a high voltage power supply design. The subsequent stage of the driven power adopts a two-direction (positive or negative) voltage doubled rectifier circuit, which can signiifcantly reduce the ripple portion of the output high voltage while improve the work efifciency of the entire driven power supply.%本文介绍了一种由锂电池驱动的便携式高压电源的设计方案，并对该便携式高压电源系统设计方案进行了仿真。本方案运用了新型双向-倍压整流电路作为整个高压电源的后级输出，该电路在降低输出电压纹波系数的同时也提高了整个电源的输出效率。
