Based on the traditional principle of two-line voltage synthesis, a modulation strategy is proposed to improve the output performance of matrix converter by changing the switching mode. According to the switching mode of the new strategy, under the premise that the input current and output voltage are sinusoidal, the modulation time of each switch of the matrix converter in one cycle is derived from the relationship between input and output current and voltage. Under the same conditions, the proposed modulation strategy is compared with the traditional two-line voltage synthesis strategy, and the corresponding simulation data and some experimental waveforms are given. Based on the research of MATLAB software simulation, the control strategy of the dSPACE hardware real-time simulation platform is experimentally studied. The simulation and experimental results verify the correctness of the modulation strategy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
