T hrough analyzing the compensation characteristics of the shunt an the series ac- tive power filters to ifferent types of harmonic sources, the suitable compensation ob- jects are etermine , the shunt or series APF shoul be use for compensating the cur- rent or the voltage harmonic source. An through analyzing the operation principles of the hybri APF, its transmit function an the harmonic current or voltages calculate formula is e uce . The experiment results show that the conclusion is correct.
