摘要
采用晶闸管交交变频方法,电机起动时能够获得小电流高转矩,本文针对晶闸管产生谐波采用可变电抗器进行滤波,通过matlab进行仿真分析,对比滤波前后谐波波形,大大衰减了谐波含量,验证了滤波方法的正确性和有效性。
It introduces a AC/AC variable frequency theory to start a AC motor to get a bigger torque and a smaller current in the thristor AC conditioning voltage circuit. It makes use of the variable inductance to get rid of harmonic. Through MATLAB simulation analysis, it reduces rapidly the harmonic ponent to prove the method vadility and availability.
