变换器

DC-DC变换器将一个固定的直流电压变换为可变的直流电压,这种技术被广泛应用于无轨电车、地铁列车、电动车的无级变速

和控制,同时使上述控制获得加速平稳、快速响应的

并同时收到节约电能的效果。用直流斩波器代替变阻器可节约电能

(20~30)%。直流斩波器不仅能起调压的作用(开关电源), 同时还能起到有效地抑制电网侧谐波电流噪声的作用。

通信电源的二次电源DC-DC变换器已商品化,模块采用高频PWM,开关频率在500kHz左右,功率密度为5W~20W/in3。随着

大规模集成电路的发展,要求电源模块实现小型化,因此就要不断提高开关频率和采用新的电路拓扑结构,当前已有一些公司

研制生产了采用零电流开关和零电压开关技术的二次电源模块,功率密度有较大幅度的提高。

UPS

不间断电源(UPS)是计算机、通信系统以及要求提供不能中断场合所必须的一种高可靠、高的电源。交流市电输入经整流

器变成直流,一部分能量给蓄电池组充电,另一部分能量经逆变器变成交流,经转换开关送到负载。为了在逆变器故障时仍能

向负载提供能量,另一路备用电源通过电源转换开关来实现。

现代UPS普遍了采用脉宽调制技术和功率M0SFET、IGBT等现代电力电子器件,电源的噪声得以降低,而效率和可靠得以提高

微处理器软硬件技术的引入,可以实现对UPS的智能化管理,进行远程维护和远程。

目前在线式UPS的大容量已可做到600kVA。超小型UPS发展也很迅速,已经有0.5kVA、lVA、2kVA、3kVA等多种规格的产品
