| 摘 要： | 分析并联有源电力滤波器开关频率对谐波补偿特性的影响.将并联型有源电力滤波器控制成一阶惯性环节,在不同开关频率时分析各次谐波与补偿特性的定量关系.在广泛应用的数字控制系统中,针对二极管整流加阻感负载和二极管整流加电感、电阻和电容负载两种典型的系统负载情况,通过仿真给出一组曲线,给出补偿后电源电流THD与开关频率的关系,得出补偿特性与开关频率的定量关系.

| Abstract: | An extensive analysis on the switching frequency to the performance of shunt active power filter(SAPF) was made.A first-order inertia element was considered as the approximate model of SAPF.The compensation characteristic for each order harmonic current was obtained at different switching frequencies.With two types of system loads which were rectifier with resistance and inductance load and rectifier with resistance,inductance and capacitance load,the THDs of source current after compensation were presented... |
