For the three phase capacitive rectifier, which was widely used in the power electronics equipment, LC filter in DC is an effective structure to improve the power factor and reduce the input harmonic current. A theory equation is derived in this paper, which shows the relationship between the input characteristics and the circuit parameter. The correctness of the conclusion is proved by the simulation and the experiment.
