The purpose of this paper is to show performance characteristics of the reference modification control dc-dc converter which uses neural network and model controls. In the presented method, the neural network controller is used to modify the reference in the proportional control term of the conventional PID control. The neural network controller is repeatedly trained using former predicted data to...
The purpose of this paper is to proposed digital controlled integral gain switchover method dc-dc converter. The integral coefficient changes for the continuous current mode(CCM) and discontinuous current mode(DCM). The integral coefficient is changed by the reactor current detection. The integral coefficient changes in the CCM using the average value of reactor current. It is confirmed that the regulation...
This paper presents a new fast response digitally controlled full bridge converter which combines the fast proportional-differential control with the FIR filter. In the proposed method, the sample timing for proportional-differential control is contrived. Thus, the delay time for proportional-differential control is minimized. The FIR filter is used in order to minimize the steady-state-errors. It...
This paper presents a new control technique for a digitally controlled buck converter. In the proposed method predictive PID control is employed in order to improve transient response and margin of stability. The application of the proposed method is demonstrated for the prototype buck converter. The frequency response is discussed and the transient response is examined to confirm the performance...
