【摘要】 变频器内部结构、工作过程以及负载的非线性使得谐波问题在变频器系统中无法避免,谐波对变频器系统本身和电源等正常工作都将造成极大的影响,在高次谐波的输入侧接入交流电抗器,交流电抗器后再加接有源电力滤波器,以及采用灵活的接地等措施能较好的解决谐波干扰问题.更多还原

【Abstract】 The inverter internal structure,process and load the problem of nonlinear harmonic distortion in the inverter system can not be avoided,harmonics of the inverter power supply system itself and the work will result in great influence in the higher harmonic input AC reactor side access,plus access after AC reactor active power filter,and the use of a flexible grounding measures can better solve the harmonic interference.更多还原
