摘要
提出了一种用于无功发生器的三级ＧＴＯ逆变器的谐波消除ＰＷＭ方法，并对此方法进行了原理分析和谐波分析，计算出在ＳＶＧ输出为不同电压值的情况下，可选择地消去一些低次谐波的ＰＷＭ触发脉冲角度值，从而提高输出电压的质量。用ＰＳＩＭ软件进行数字仿真，其结果验证了理论分析的正确性。
A new programmed PWM technique to selectively eliminate several lower order harmonics at the output of a static VAR generator(SVG) with three level GTO inverter is investigated. Theoretical description and harmonic analysis are presented. Switching angles for selective elimination PWM with various output voltages of SVG are given. Analysis have been verified with PSIM simulator.
