Multi-MHz High Frequency Resonant DC-DC Power Converter

By: Dianguo Xu,Yueshi Guan,Yijie Wang,Xiangjun Zhang

This book analyzes multi-MHz high frequency resonant DC-DC power converters with operating frequencies ranging from several MHz to tens of MHz in detail, aiming to support researchers and engineers with a focus on multi-MHz high frequency converters. The inverter stage, rectifier stage, matching network stage are analyzed in detail. Based on the three basic stages, typical non-isolated and isolated resonant DC-DC converters are depicted. To reduce the high driving loss under multi-MHz, resonant driving methods are introduced and improved. Also, the design and selection methods of passive and active component under multi-MHz frequency are described, especially for aircore inductor and transformer. Furthermore, multi-MHz resonant converter provides an approach for achieving flexible system.

Older People and their Household-Related Life Satisfaction in Germany

By: Xiangjun Ren

Quality of life is an issue which has drawn the attention of scholars, politicians and the general public since ancient times. Along with the development of social indicator research after the 1960s, life satisfaction became one of the main assessments in measuring one’s quality of life. Against the background of ageing in the European scale, the household has become a significant dimension for older people. Due to changes in social culture and personal living arrangements, the role of the household in providing older people with a better later life is reducing rapidly. Therefore, this book takes older Germans as the typical group and analyses their life satisfaction from the perspective of the household-related life domain. With a series of quantitative statistics, some of the findings are outside expectations. This book with its interesting findings is a worthy read for scholars and college students in relevant fields. Besides, this book may also be attractive for older people who are concerned about their own later life.
