Abstract :
The complete circuit dq transformation of a three phase AC-DC MC, namely matrix rectifier (MR) system, is derived by utilizing circuit dq transformation technique and input current space vector algorithm. Then the model is partially differentially linearized, and the AC small signal circuit model is obtained, so is the state equation of matrix converter system. Based on the system signal-flow chart, the transfer functions of output variables to input variables are derived, then the dynamic behaviors of open loop system is analyzed theoretically. The above theoretical analysis is proved by the simulated results, laying the foundation for further system design. But the case of slightly unbalanced input voltages in practical applications is not considered here
