| 摘 要： | 对并联混合型有源电力滤波系统的构成和工作原理作了分析研究，它是由小容量有源滤波器通过变压器和无源滤波器串联构成的，并与被补偿的谐波负载并联连接。基于。TMS320F240 DSP的开发套件，采用脉宽调制(PWM)定时器下溢中断工作方式，设计了数字控制器主程序和中断服务子程序。设计的一套实验系统用来消除谐波负载产生的谐波影响。实验结果表明，有源电力滤波器投入后，电网谐波电流得到了有效的抑制。

| Abstract: | The configuration and working principle of a parallel connection hybrid type active power filter are studied.The hybrid filter is made of a small rated active filter through the a series-connection between transformer and reactive filter,then installed in parallel with the compensated harmonic load.Based on TMS320F240 DSP exploiture tool,a main program and some interrupt subprograms of a digital controller are designed by using PWM timer underflow interrupt manner. The digital controller programs easily and intuitively,operates precision highly,adjusts parameters expediently,and is easy to realize all kinds of control tactic.A combined power filter test system is designed,which is used to clean up harmonics of harmonic load.The experiment results indicate that the harmonic currents can be compensated effectively when the active power filter system is operating. |
