| With the development of the green power technology, PWM four-quardant rectifier has become a highlight in the field of power electronics. Due to the merits of pollution-free adjustable power factor and bi-direction power transfer, the PWM four-quardant rectifier can be an ideal electric appliance or a linkage between grid-line and other electric facilities.This dissertation focuses on the engineering design and realization of high power three-phase Voltage Source Rectifier (VSR) with emphasis on the control technique. The dissertation work, covering the methodology study, controller design, prototype implementation and experiment, is presented as following.Firstly, the paper discusses the principle of the three-phase Voltage Source Rectifier (VSR).On the basis of deriving the rectifier's mathematical model, the control ways are summarized and their features are pointed out. The paper works at the control algorithms mostly. The theory and the control way of the voltage space vector PWM (SVPWM) are described in detail. Adopting non-standard vertical reference frame to judge the vector sector and calculate the action time. The ways make the calculate load of the SVPWM reduced and more easily digital applied.In the paper, the designing method of the parameter of the main circuit is also described. The controller's hardware was designed around the Ti's TMS320LF2407(DSP) processor and corresponding software was also designed to integrate with the hardware to realize a dual-loop three-phase VSR control system.At last, the whole simulation module of control system is built up under the power MATLAB/SIMULINK platform and the above several ways are used in the simulation module. The result of the simulation proves that control ways are right and feasible. At the same time, from the concrete analysis, the rectifying system applied the simple algorithm can make the power bi-directional flow. Moreover, its control algorithm is easy and the range of DC utilizing efficiency is large.
