Abstract EN
The paper presents a new algorithm for determination of pulse edges of a modulated wave of a PWM voltage inverter which offers a possibility that natural sampling is realized with an arbitrary accuracy without applying an iterative procedure.
The basic idea is to express the angles which determine pulse edges of the modulated signal as polynomials of amplitude modulation index.
Geometric interpretation of sampling of the polynomial algorithm is identical with the geometric interpretation of natural algorithm, but the transcendental equation whose solution defines pulse edges of the modulated signal is replaced by a simple procedure of finding values of a polynomial whose coefficients are determined in advance by an exact procedure.
This approach gives the possibility of digital implementation of polynomial sampling method using the low-cost microprocessor platforms.
