This paper presents a review on digital pulse width modulation methods (PWM). The review is carried out by complexity comparison of various modulation schemes. New methods introduced as weighted PWM (WPWM) and with error correction (WEE) are proposed for high performance, easy to implement, modulator implementation. A newly developed digital PWM simulation platform for MATLAB (DPWMSIM) is furthermore presented.
