Abstract :
An adaptive hysteresis current control technique where the hysteresis band is automatically modulated by the input voltage integrator without the load information to maintain the modulation frequency nearly constant is presented. The computer simulation for the proposed current controller has been carried out and the results show good static and dynamic performances.
