| 摘 要： | 通过对电压源逆变器输出脉冲序列函数的傅里叶分析,推导了并联型有源电力滤波器数字控制系统中心对称规则采样方式的调制误差模型.在此基础上,提出运用一种基于自适应预测算法的准自然采样脉宽调制方法,精确逼近自然采样调制过程,从而有效抑制有源电力滤波器实际输出电流相对于理想补偿函数的相位偏移与波形畸变,显著提高了有源电力滤波器对...

| Abstract: | The modulation error model of central symmetrical regular sampling for digitalized shunt active power filter(APF) controller was deduced using Fourier transformation for output pulse series function of voltage source inverter.Furthermore,a quasi-natural sampling pulse width modulation(PWM) method based on adaptive prediction algorithm was carried out and employed to precisely approach natural sampling modulation process,hence to efficiently suppress the phase excursion and waveform distortion of harmonic co... |
