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、快速响应的性能,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技术,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。
