在激光技术领域中,充电机往往是不可缺少的设备之一.随着激光技术的发展,充电机也在不断改进,根据不同的用途,研制出了多种类型的充电机.最初使用的恒压充电机逐步淘汰而代之以恒流充电机.前者的充电效率最高也不超过50%,而后者的充电效率大大提高.恒流充电机的类型及其原理也有好几种.这里简要地介绍一种电感-电容型(以下简称为L-C型)恒流充电机.这种充电机的特点是:充电效率高,一般可达86%左右,理论上可达95%左右;功率因数 cos￠ In the field of laser technology, the charger is often an indispensable device.With the development of laser technology, the charger is also constantly improving, according to different uses, developed a variety of types of chargers. The initial use of constant Compression charger phase-out and replaced by constant current charger.The former charging efficiency is not more than 50%, while the latter greatly improve the charging efficiency. There are several types of constant current charger and its principle. Here briefly Introduce a kind of inductance - capacitance type (hereinafter referred to as LC type) constant current charger.The characteristic of this kind of charger is: Charging efficiency is high, generally up to about 86%, theoretically up to about 95%; The power factor cos ¢
