摘要
为解决PWM功率放大器输出长线传输引发的波形畸变,可能伤及力矩电动机的问题,对实际系统结构进行了理论分析,找出了可能引发波形畸变的原因,并给出了3种解决方法。实际试验结果证实所给方法的有效性。
When transmitted through long cable, the output of PWM power amplifier may be distorted. The distorted wave may damage torque motor. By analyzing system at work, the factors caused distortion are found, and three solutions are presented. Experiment result shows that these solutions are valid.
