Modularization active power filter

The utility model discloses a modularization active power filter, its characterized in that: wave filter voltage and the electric current equisignal of gathering the mainboard including the sampling board transmit for the control panel, the IGBT drive plate obtains direct drive IGBT behind the pulse signal from the control panel, installation direct current electric capacity and IGBT module on the mainboard, the electric wire netting is exported with the harmonic compensation of realization to the electric wire netting with alternating current signal to output reactance ware board connection mainboard. Since the above structure is adopted, the utility model has the advantages of it is small, simple to operate, the operation is reliable, and control is nimble, and detection and protect function are perfect. 本实用新型公开了种模块化有源电力滤波器，其特征在于：所述的滤波器包括采样板采集主板的电压和电流等信号传递给控制板，IGBT驱动板从控制板获取脉冲信号后直接驱动IGBT，主板上安装直流电容和IGBT模块，输出电抗器板连接主板将交流信号输出到电网以实现对电网的谐波补偿。由于采用上述的结构，本实用新型具有体积小，安装方便，运行可靠，控制灵活，检测和保护功能完善等优点。
