In this paper, we present a new method of the PWM signal generation with repetition of data segments, based on the round robin segment of different amplitudes converters, applied to the photovoltaic water pumping system and the variable frequency variable voltage systems, in order to use the data stored signals to generate other signal amplitudes intermediate to optimize memory usage and reduce the cost of the control board.

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. General TermsPulse width modulation.
