A fast stable control scheme for VIENNA rectifier

This paper establish the mathematical model of VIENNA rectifier in d-q synchronous reference frame, after analyzed the variables´ relationship and all of the switches on-off states and then proposed a novel scheme for fast response of VIENNA rectifier. And transfer the result signal into a-P coordinate to analyze the relationship of the signal. At last changing the components to achieve faster response, which also discovered that the proposed scheme have a better stability. Simulation results shown that the proposed control scheme had satisfactory steady-state characteristics and fast transient response. This control scheme possesses some practical values due to its simpfast transient responsele implement.
