Abstract:
For the three-phase to two-phase matrix converter (3-2MC) without large-capacity energy storage components, the output asymmetry affects the input current quality. To deal with this problem, we present a class of three-terminal and four-terminal output 3-2MC topologies with pulsating power compensation unit. Firstly, the principle, the realization process and the application range of the two kinds of converters to suppress the output pulsating power and improve the input performance are described in detail. The relationship between the voltage transmission rate and the system parameters of the four terminal output 3-2MC is deduced. Based on the characteristics of the topology, the output sector division method is proposed. Then, a cascade control strategy is proposed, taking the output side and the compensation side three-phase current weighting amount as the indirect control quantity, and the feasibility is analyzed theoretically. Furthermore, an optimization method of system control parameters is given. The simulation results show that the four-terminal output 3-2MC topology based on the indirect control strategy can effectively improve the input current performance under asymmetric output. Compared with the traditional three-terminal topology without pulsating power compensation unit, the proposed method has good dynamic performance and more large output range.
