| Abstract |
A general approach for the analysis of AC-AC direct converters is presented which allows the performance of three-phase matrix converter to be evaluated even in the case of input and output unbalanced conditions. The control strategy is based on space vector modulation technique and performs in order to keep the input current vector in phase with the input voltage vector. The maximum voltage transfer ratio and the harmonic components of input line currents are determined analytically as function of input and output voltage unbalance degree. It is verified that in the case of input unbalance non-sinusoidal current are obtained having only positive sequence harmonic components, while positive and negative sequence components may be present under input and output unbalance. Simulated results are given to confirm the analytical approach. |
