手持式放射性环境监测仪的双极性电源研制

The Development of Ambipolar Power Based on One Handhold Radioactive Environmental Monitoring Instrument

手持式电子产品设计的一个核心部分就是电源的设计。手持式电子产品一般要求能较长时间地野外工作,这就要求电源有较高的转换效率、较低的静态功耗、较好的负载特性及较小的电源纹波;而且,系统需要将一些弱小的信号放大、变换、滤波和处理。为了降低整个系统的静态功耗,双极性电源就有存在的必要性。阐述了一种基于手持式放射性环境监测仪的电源研制,该电源具有良好的特性,同时具备强大的适应性,也可以适用于其它类型的手持式电子产品。

The core apartment of a handhold electric productions designing is the designing of the power. It is a general requirement that the handhold electronic productions can work a long time in field operation, so it calls for the power has the higher conversion efficiency, low power＇s quiescent dissipation, good load characteristics and small power source ripple. Furthermore, the system has to make weak signal amplified transformed filtered and processed. For reducing the quiescent dissipation of the system , so it is necessary to exist for the ambipolar power. The paper precisely elaborated on development of power, it was used on one handhold radioactive environmental monitoring instrument, this power has a good characteristic, simultaneously has a formidable compatibility, may be suitable for other handhold electronic products.
