| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper discusses the switching operation for higher conversion efficiency and seamless control for wide range of the input voltage in a H-Bridge DC-DC Converter．This converter consists of buck and boost blocks and a feedforward control from the input voltage is employed for the boost block to realize seamless transition between step down to step up operation mode. From the view points of the switching loss and the internal ohmic loss，two methods of different switching frequencies and the desirable duty ratio of the boost section are examined. As a result, higher efficiency was obtained by reducing the switching frequency of the buck block without increasing output ripple voltage and by minimizing the duty ratio of the boost block for wide range of the input voltage. | |
