doi:10.16628/j.cnki.2095-8188.2024.02.008

Abstract

Abstract:

A single voltage loop multiple proportional resonance (PR) control strategy is proposed to address the difficulties of proportional integral (PI) controllers in achieving zero static error control of output voltage and low order harmonic suppression.The characteristics of the PR controller is analyzed, a design method for PR parameters is provided, the simulation verification using MATLAB is finished, and the experimental verification on a 2 kVA prototype is conducted. The results show that the proposed strategy can achieve the complete elimination of specific harmonics, the total harmonic distortion of output voltage less than 1%,and the good steady-state and dynamic performance.

Key words: 400 Hz power, zero-steady-error control, low order harmonic suppression, multiple proportional resonance(PR)
