Abstract

This paper presents a discrete nonlinear control scheme for PWM inverters. Based on the dynamic model of the PWM inverter a control algorithm is deduced by imposing a desired linear dynamics in the output voltage. The proposed scheme has shown its robustness on low voltage distortion, excellent voltage regulation and it is insensitive to load and input voltage variations. A simple and fast digital algorithm, that could be implemented on a low-cost DSP, carries out the discrete control.
