Abstract

With the wide application of power electronic equipment, more and more attention has been paid to the power quality of power supply system. For three-phase/switch VIENNA rectifier with a high power factor, one cycle control is a reliable and simple non-linear large signal control method. For the design of VIENNA rectifier, the balance of dc-link neutral-point voltage is important, especially when DC side is connected to unbalance load. This paper puts forward a new neutral balance control algorithm based on one-cycle control of VIENNA rectifier and improves the current three-phase/switch one-cycle control algorithm, making it fit with the realization of discretization.
