A Novel Sampling Method of SPWM with Nonsymmetrical Rules

A nonsymmetrical rules peak sampling method,which enables the width of pulse closer to the nature sam-pling method is presented.Moreover,this novel sampling method could be implemented in digital controller with only one sample in every carrier wave cycle,which is better than traditional sampling methods.What's more,the paper presents a simulation method on the peak sampling method with Simulink,which is easy and well adapted to many occasions.The simulative results and the experimental tests verify the effectiveness of the proposed sampling method.
