Abstract
Contraposing the shortcomings of natural sampling method that has to solve complex transcendental equation and is difficult to achieve real-time control, this paper presents a method that using binary search to solve SPWM switching points based on natural sampling method. This improved algorithm is programmed using C language and simulated in MATLAB environment by C-MEX file. The result confirms its effectiveness and feasibility.
