Abstract :
A simple microprocessor-based current regulator for pulse-width-modulated (PWM) transistor inverters is presented. The control strategy is based on the discrete delta modulation principle. The originality of the technique resides in the sampling method used for the delta-modulation-based current regulator. The design of the system with application of an SAB80C535 one-board microprocessor controller is discussed. Simulation and laboratory tests results showing the properties of the current regulator are presented
