In this paper, the results of examining the number of strands for high efficiency and low heat generation of litz wire used for transformer of LLC resonant converter are described. Converter used for switching power supplies are required to be smaller and more efficient. To reduce the size of the converter, examinations have been made by increasing the frequency of the driving frequency. However, due to the high frequency, heat generation in the winding increase due to an increase in AC resistance in the transformer, which is one of the programs of high frequency. In view of this, we study reduction in heat generation by making the wire diameter of the winding constant and changing the number of strands. As a results, it is possible to improve efficiency of the LLC converter by 0.3 % and suppress heat generation of the transformer at 37 °C.

<p> Linear DC motors often fit the drive field of which you request single stroke fast response below the 100 mm in particular. It is necessary to make the servo gain increased to drive LDM by fast-response. But displacement of LDM is easy to oscillate in increased gain. Amount of displacement is increase by pitching of LDM. It is desirable to install the displacement detection sensor at a position not affected by pitching behavior. This paper introduces the displacement detection position not affected by pitching.</p>
