Abdelaali Boumaaraf, Tayeb Mohamadi, Mohamed Djamel Draou . Optimization of the Repeated PWM Command Applied to the Variable Voltage Variable Frequency (VVVF) Converter. International Journal of Computer Applications. 24, 2 ( June 2011), 1-7. DOI=10.5120/2926-3869
A new technique of generation signals of the RPWM (repeated pulse width modulation) command have been proposed, by using an alternated and variable repetition of data segments of a reference PWM signal applied. The mathematical aspects and the spectral analysis of this technique are presented as well as the hardware to concretise it. So a optimise concept of this generation will be presented, based independently on the generation of signals command of micro-controller in the aim to reduce the time allocated by this last and to minimise the number of addresses lines between the micro-controller and the memory.
