Abstract

In this paper, a novel filter structure is proposed based on the sequence of PWM voltage harmonics. At first, the phase of voltage harmonics is thoroughly analyzed. Based on the phase difference between three phases, it is shown that the sideband harmonics can be divided into positive-sequence, negative-sequence and zero-sequence components. Through 120° interleaving and three paralleled converters, the positive-sequence and negative-sequence voltage harmonics can be synchronized to have the same phase. With the synchronized phase, the voltage harmonics can be suppressed by the proposed filters, which have an identical structure to the threephase common-mode choke. Furthermore, considering the phase difference, the proposed filters can be integrated as a three-limb core which gives an additional size reduction. The validity of the proposed filter is verified through the simulation and an experiment.
