Abstract

© 2015 IEEE.Recently, the energy saving is required. It is necessary for the energy saving to operate the electric device in the sleep mode. Therefore, the output voltage rises abnormally because the DC-DC converter is required the operation in the discontinuous current mode. Therefore, we have proposed the model control using static model and strived for improvements. In the proposed method, the output voltage is stabilized because the operating point is changed. Therefore it does not depend on the integral coefficient in principle to perform wide output voltage stabilization range. Actually, the steady state deviation remains because the model equation includes the error in the analysis. The integral control compensates it. In this paper, the static model equation and integral coefficient in the proposed method are considered based on the output voltage stabilization range.
