A SVM method based on active area vector

A modulation analysis method based on active area vector (AAV) is introduced via analyzing the switch pulses characteristic, and a novel pulse generation method of SVM is presented by applying the AAV in SVM. The corresponding relationship between AAV and switch pulses is built, and the equivalent transformation relation of different AAVs is derived, which has the same modulation effect with conventional SVM, however, the new method will simplify the modulation process, solve the problem of computation complexity for conventional SVM, and provide theoretical support to improve the characteristic of SVM or develop other new modulation method. AAV based SVM can be realized by digital signal processing chips easily, have advantages such as simple control, reliable performance and good transplantation. The validity of the proposed method is verified by simulation and experiment results, the SVM based on AAV can greatly simplify the modulation process, decrease the computation complexity, and create conditions to enhance inverter bandwidth, reduce sampling cycle, and improve the quality of the output waveform.
