电源技术 优化输电线路 精确测量电压驻波比(VSWR)

Abstract: Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss andreflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line imperfections. Thistutorial defines VSWR and explains how it is calculated. Finally, an antenna VSWR ...

电源技术 逆变电路的基本工作原理

单相桥式逆变电路为例:S1~S4是桥式电路的4个臂,由电力电子器件及辅助电路组成。S1、S4闭合,S2、S3断开时,负载电压uo为正S1;S1、S4断开,S2、S3闭合时,uo为负,把直流电变成了交流电。改变两组开关切换频率,可改变输出交流电频率。图5-1 逆变电路及其波形举例电阻负载时,负载电流io和uo的波形相同,相位也相同。阻 ...
