Abstract

The quality of output waveform is one important factor for the single-phase inverter.This paper proposed the algorithm based on neural network internal model theory

which is used for an output sine waveform control.Based on this control algorithm

two back propagation estimate neural networks were established.One is the internal model of single-phase inverter

which is used to estimate the actual output waveform.The other one is used to make the internal model to fit the actual single-phase inverter due to the estimate error.We finished the simulation and experiment

where the algorithm was proved that it could improve the output waveform quality and load compatibility.
