摘要：

This paper proposes a current compensation method for current reconstruction from a DC-link current sensor. The method has region in which phase current reconstruction is difficult. To solve this problem, voltage reference and carrier compensation methods have been proposed. However, these methods increase the phase current harmonics. This paper proposes a current compensation method that uses the phase difference between the current and the voltage reference. The effectiveness of the proposed method and characteristics of reconstruction current feedback control are confirmed using a simulation. Experimental results verify the validity of the proposed current reconstruction method.
