Analysis of Harmonics in Input Line Current for Matrix Converter based on Double Input Line-to-line Voltages

Control strategy on double input line-to-line voltages for matrix converter was studied fewer compared with others. The relative theorem and inferences are put forward. That is the general composition rules and expressions of input line current is gotten. The simulated model was setup based on this modulation strategy. The simulated experiments have verified correctness of the theorem and inferences, and have gotten the harmonics distributed rule of input line current with harmonics in input voltages
