交直流兼用的高性能GTO多重电流型脉冲变流器

A High Performance GTO Multiple Pulse-width Controlled Current Source Converter

本文研究了GTO电流型脉冲变流器及其多重式结构方案。它可以从交流电网吸取功率因数接近1的准正弦波电流,输出为可调的恒定直流;并在大容量装置中显著减少应用单个电流型脉冲变流器时交流侧的储能电容。既可以直接驱动直流电动机,也可以经由电流型逆变器供电给异步电动机;适用于大型设备或电力机车。

A GTO pulse width controlled current souree converter and the implementation of its multiple unit for a.c./d.c.drive are studied.It obtains a pseudo-sinusoidal waveform current with.osφ≈1 from the a.c.Ine.Its output is a controlled direct current.It can greatly decrease a.(?).capacitor at the power supply side of a convtrter.It can directly drive d.c.motor or provide power supply for induction motors through CS(?).It is promising in the application area of electric locomotive and other powerful drive.
