Abstract (in Japanese) (See Japanese page) 
(in English) Proposed divided power supply system for server system is making use of two bus voltage levels such as 12V and 32V. In the case of the low power loads, the power is supplied from POL converters with 12V bus in the same manner as the conventional intermediate bus architecture. On the other hand, in the case of the high power loads such as MPUs, the power is supplied from two-stage converters with the both bus voltages. The two-stage converter consists of a low power buck converter and a high efficiency high power density isolated converter. In this paper, efficiency and transfer characteristics are experimented with manufactured isolated converters.
