output isolation meaning in English

输出隔离

A novel high - power pollution - free smps is presented in this paper , which accomplishes simultaneously the goal of soft - switching pwm , the input / output isolation , the output voltage regulation and three - phase pfc with a single - stage power processor and simple pseudo - phase - shift control circuit . therefore , compared with the normal two - stage system , the single - stage power supply has simpler structure , lower cost , higher efficiency and easier to control . the proposed smps can be used in the three - phase power system , and can output high power over kw - order and input / output ( i / o ) isolation dc power supply
本文提出的新型无污染大功率开关电源正是采用三相三线制输入电源，利用单级伪相移零电压零电流开关脉宽调制( pps - zvzcs - pwm )全桥变换器完，成功率因数校正( pfc )和输出电压快速调节、隔离的双重功能，并且该变换器开关管在零电压或零电流下通断，显著的减小了emi 。
