This paper presents the programming and use of TMS320F2812 digital signal processor (DSP) in generating the digital pulse width modulation (DPWM). The structure and functions of eZdsp 2812 board used in this work is explained briefly and the steps need to be taken for the programming is explain in detail to control the frequency, the duty cycle and dead band of the generated PWM. The PWM generated...
Pulse-width modulation (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. This paper presents work on modelling and simulation of modified unipolar PWM applied to a single phase DC-AC converter (inverter) as switching control schemes. The harmonic analysis for switching...
