Brief Analysis of Modeling Methods of AC-AC Matrix Converters with Novel Topology

The basic principle and space vector modulation strategy of AC-AC matrix converters are described briefly. The real realization process of space vector modulation algorithm is analyzed in detail. The two kinds of simulated models were set up by means of MATLAB language and SIMULINK toolbox respectively. The simulated results show that the two kinds of models have their own properties respectively. The former is mainly fitting for verifying their excellent properties and feasibility of modulation strategies; the latter is approach to the actual system, gives theoretical instruction, and also verifies the correctness of modulation strategies. In a word, the two methods can compensate and verify each other, which may be chosen according to the actual things. What’s more, they have extending properties and are worth developing.
