Design and Implementation of a Dynamic Evolution Controller for Single-phase Inverters with Large Load Changes

Abstract

Abstract—A new controller is developed for a single-phase inverter based on the dynamic evolution control method. The non-linear model equations and algorithm of the approach is derived and presented. The simulation is conducted based on the proposed method by MATLAB/Simulink to test the performance of the controller for large load variations. The system was also tested experimentally to show the feasibility of the proposed method applied to a single-phase inverter. Results show that the proposed approach is suitable for applications with large load variations. Practical results show that the controller can successfully handle a 40 times load change in less than 2 ms. It also has good output in the harmonic spectrum compared with the IEEE 519 harmonic standard during no-load and full-load conditions.
