 note = {Among various type circuits, the buck-boost type dc-dc converter have been widely used as power supplies for electronic systems, in which the output power is relatively small under 100 W, because of its simple circuit construction, small number of components, and the isolation between the input and output. However, the back-boost type dc-dc converter has a deteriorative problem in practical use that the output voltage of the dc-dc converter increases extraordinarily when the reactor current is discontinuous under the light load condition. The purpose of this paper is to present a new control method to solve the above problem, in which the digital control circuit is composed of digital circuit and its feedback gain is changedover as the operation mode of the dc-dc converter varies, and to analyse the output characteristics of this digitally controlled dc-dc converter theoretically. As a result, the regulation and dynamic characteristics are clarified and the regulation characteristics is improved in the discontinuous reactor current region., 長崎大学工学部研究報告 Vol.25(45) p. 113-117, 1995},
