[Abstract]:Firstly, the mechanism of low frequency pulsation current suppression is analyzed in detail. Then, taking the two-stage inverter as an example, based on the input of DC power supply, the former stage DC/DC converter, Four positions of DC busbar capacitor branch and rear inverter are described in detail, which mainly include control strategy and topology optimization. The basic idea of low frequency pulsating current suppression method for single phase inverter is summarized, and the technical principle, advantages and disadvantages of the existing methods are analyzed and discussed. By comparing and analyzing the characteristics of the existing low frequency pulsating current suppression methods, the direction of the following research is pointed out. Taking a new type of Boost inverter as an example, the effect of the new control strategy on the input low frequency pulsating current is verified by experiments.
