Abstract
This paper analyzes the working principle of VIENNA rectifier and establishes the transformation model of rectifier in three different mathematical coordinate systems. First is to obtain the control structure of the converter, which is a double closed loop control structure (the voltage is the outer loop control and the current is the inner loop control). By using a feed forward control strategy to solve the problem of phase-to-phase coupling. By adding the voltage equalization loop and using the midpoint balance algorithm to solve the problem of the voltage imbalance caused by the rectifier under load. Finally, uses MATLAB to build the model, simulates and verifies the established model system.
