便携式计算机电源的系统适应性研究

Study of the Adaptability of the Pocket Computer AC Adaptor

从便携式计算机的电源能否接在飞机电源系统这个实际问题出发,研究了便携式电子设备的电源及其充电器的适应性问题。首先根据整流理论进行了适应性论证,然后进行了计算机电源在400Hz频率系统的空载和加载试验,理论分析及试验数据结果表明,这种装置对400Hz电源系统是适应的,输出参数符合原设计要求,没有发热、振动等不良现象,可以使用。因此在新设计的飞机上,供旅客使用的电源,不必专门提供工频电源系统接口。

Proceeding from the practical problem of whether the electric system of an aircraft, the paper studies the pocket computer AC adapter can be connected with the power source of the pocket electronic equipment and the adaptability of its charger, First adaptability is expounded and proved in accordance with the theory of rectification, Then experimental study is conducted with results showing that if the pocket computer AC adaptor is plugged in the 400 Hz electrical power system,its voltage output ability keeps unchanged. Further,the heating and noise are not found. The conclusion is that the AC adaptor is applicable in aircraft. This experiment leads to two benefits：one is that the pocket computer can be plugged in the socket of an aircraft;another is that there is no need to design additional 50 Hz or 60 Hz electrical inlet in the aircraft.
