A new microcontroller-based technique for generating variable voltage/frequency sinusoidal PWM signals

Mathematical modelling of sinusoidal pulse width modulated signal and its implementation on microcontroller based embedded system

“…A fully digital EPROM-based pulse width modulator (PWM), which receives voltage and frequency control commands independently at the input for generation of ac variable speed drives, is described in [3]. A flexible and robust microcontroller-based technique for generating the control signals of any sinusoidal pulse width modulation (SPWM) scheme for variable voltage/frequency output is described in [4], where controller's clock was used for generation of PWM control signals. An Intel 8086 microcomputer-based pulse width modulator (PWM) is described in [5], which receives digital voltage and frequency commands independently at the input, generates precision three phase PWM waves at the output.…”
