The utility model discloses a mixed type harmonic suppressor, mixed type harmonic suppressor's structure is established ties by active part and passive part and is constituteed. This topological structure active part mainly includes direct current lateral capacitance C, voltage type converter, output filter inductor L1 and shunt capacitance C1, passive part is mainly become by the passive power filter fabric that L2 and C2 constitute. Most grid voltage is undertaken to passive part, can effectively reduce active part operating voltage to reduce the capacity of active part, the function that restraines specific harmonic current size is undertaken to the active part. The uncontrollable defect of current passive filter electric current has been solved in active part and passive partial organic combination.
