The structure and working principle of the injection type hybrid active power filter (IHAPF) are analyzed, and the optimization design of the main circuit parameters is emphatically discussed. A passive filter design method is proposed, Which not only meets the requirements of harmonic control but also ensures the reliable operation of the device. An optimal design method of injection branch parameters based on Particle Swarm Optimization is proposed, which can reduce the harmonic suppression of IHAPF and reduce the influence of grid harmonic voltage on device reliability . A set of IHAPF is developed for the actual condition of rectification device causing reactive power shortage and harmonic pollution in an enterprise. The simulation analysis and engineering application show that the IHAPF can effectively carry out harmonic control and reactive power compensation and meet the requirements of the enterprise Claim.
