| Abstract | From a cost-effective point of view, it is very important to design current controllers with the highest utilization factor of current capacity of power devices. This can be accomplished by a current controller without overshoot irrespective of the varying bound of control voltage in PWM power converters and the dead time due to the time delay. This paper suggests a novel current controller with delay compensator which has fast control response without overshoot and also deals with the design method of the controller for PWM power converters. Extensive simulations performed using SIMULINK/MATLAB show that the suggested controller guarantees the full utilization of current capacity of power devices and the decoupled current control behavior |
