A DQ Synchronous Reference Frame Current Control for Single-Phase Converters

Abstract

This paper presents a current control using the dq synchronous reference frame for single-phase converters. This control method consists in transforming an orthogonal pair composed by the actual single-phase input current and a fictitious current, from a stationary to a rotating frame. The steady state current components in dq frame become DC instead of AC values so a zero error current control can be implemented. A single-phase PFC boost rectifier is used as an example application of this control. To validate the control method simulation and experimental results are presented
