Abstract

This paper presents a new hysteresis current control technique for a three-phase inverter based on magnitude and time errors. Twelve comparators measure current errors in three phases in such a way to minimise the switching frequency and to provide a better solution to decide adjacent voltage vectors. The advantage of this method is a fast decision and simple control circuit to select the switching states in “ABC” coordinates without prediction of back emf or the derivative of the reference currents. Theoretical analysis and simulations results verify the proposed method.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
