Study on Shunt Hybrid Active Power Filter

A scheme of shunt hybrid active power filter(HAPF) was introduced.The basic principle of HAPF was expounded.The control strategy for active power filter suppressing harmonic,which integrates merit of current harmonic control mode for inspecting load and power grid.The mathematic model of complex control technique was given.The practice shows that presented HAPF and control mode have merit of good filtering effect and high dynamic performance.
