In this paper, the already proposed high feedback gain switching method has the optimum setting for a specific load step. Therefore, we investigate the optimal setting of the proportional gain switching for various disturbance such as the line and load fluctuation, which could occur in the renewable energy system. As a result, the following setting of the proposed method is optimum: the optimum setting...
In this paper, we present a feedback gain changing dc-dc converter. The proposed method corresponds to the input voltage variation because the integral gain is determined in consideration of it. Generally, a quick transient response cannot be obtained when the proportional gain is small. On the other hand, when the proportional gain is set to a large value, the transient response is improved. However,...
In this paper, we present a new quick response digital control dc-dc converter based on a dynamic unstable gain to improve transient response. In the proposed method, the proportional gain is set to the small value in the steady state and the large value over the stability limit for only a short time in the transient state. Compared with the conventional PID, the undershoot, the overshoot and convergence...
