The purpose of this paper is to obtain the high performance modulation that combines all features in one: the power efficiency, the robustness to switching disturbances and the currents balancing under an unbalanced load. Due to the high power efficiency, this type of modulation is very attractive for high dynamic applications such as electrical vehicles. The performance efficiency of the proposed...
The strategy of conventional space vector modulation (SVM) is based on the assumption of ideal power commutations. In reality, the power commutations are under switching disturbances that leads to the appearance of distortions into the output current. The reduction of the current distortions is available due to obtaining the robustness of SVM based on redundancy. The robust SVM with minimum distortions...
The modulation strategy with the current invariance to input voltage disturbances and novel modulation algorithms for two-stage direct power converter are presented. Based on theoretical approach, the conditions for getting the current invariance are obtained. The novel modulation algorithms with minimum input current distortions are developed according to the proposed strategy. The switching sequence...
