Abstract
In this paper a new adaptive hysteresis current controller for PWM inverter applications is presented. The proposed system adapts the hysteresis band and chooses the switching pattern according to fuzzy logic rules. The resulting controller operates at nearly constant switching frequency, ensuring optimum switching pattern choice, and can be digitally implemented by using a standard microprocessor. After a detailed description of the proposed system, simulation results are presented
