Development and Implementation of a New Kind of SPWM Sampling Method

Article Preview

Abstract:

Based on the analysis of the method of natural sampling, symmetry regular sampling and all kinds of asymmetry regular sampling, a sampling method based on MATLAB and MCU is presented in this essay, which is called digitized quasi-natural sampling method. With the use of the powerful operation ability of MATLAB in this method to calculate the numerical value required in advance, much more operation burden of MCU is reduced , then MCU can do the control easily according to the value presented. By the division of labor cooperation the calculation precision and control speed can be ensured at the same time, thus very strong practicability does the digitized quasi-natural sampling method have.
