Abstract:
In power electronic power conversion device, high power factor voltage type rectifier device because of its high power factor and harmonic less widely used. This paper discusses the three phase voltage type rectifier in ABC, alpha beta and dq coordinate system of the mathematical model. The space voltage vector control strategy and direct power control strategy has carried on the system analysis, the use of Matlab simulation software Simulink module established the simulation model, get the correct simulation results. The innovation of this paper lies in the direct power based on the theory of, will control switch table is divided into active and reactive two, make system startup performance improved. And the application of Matlab simulation software Simulink module established the simulation model, get the simulation results prove the correctness of the theoretical analysis. Finally, the paper puts forward the direct power control system of the main circuit parameter design, and application of Matlab simulation software Simulink module established the simulation model, obtained the accord with the expected simulation results show that this control strategy correctness.
