Power Electronics as the Key Technology for a Better Future January 17th, 2014 At Maranatha Christian University, Bandung, Indonesia Abstract: The demand of electricity has been increasing in the World. Our convenient lives have been deeply based on electricity. Therefore, electricity is essential for a better future. Form of electricity (voltage level, frequency, or AC/DC) should be suited to its loads in power systems. Because of this, form of electricity should be converted. Of course, sustainable energy resources, highly efficient transportation, and even information technology have been strongly based on the electrical power conversion, too. The form of electricity is changed by power converters, like AC adapters, inverters, or power conditioners. And, the power converters are based on Power Electronics technology. Power Electronics technology is using switches (semiconductor devices) and energy storage (inductors and capacitors). Because of using switching, loss in the power converters is quite low. But actually, it's still not enough low to use much more amount of electricity. In addition, components for the energy storage are bulky. So, the reduction the size of the components is required. As for the size reduction, it is useful to increase the switching frequency of the switches. But, as the switching frequency increases, loss and EMI in the converters also increase. Because of the loss and EMI, it is very difficult to reduce the size now. Thus, it is necessary to improve both the semiconductor devices, components for energy storage, and integration design. Therefore, we should open our eyes to other field of research, like material technology and integration technology, and so on. ]]>

https://cdn.slidesharecdn.com/profile-photo-mkamaga-48x48.jpg?cb=1523074573 I was a researcher of power electronics (Ph.D), but strongly felt that technology has been just a tool for making better solutions to society. Then I thought that it's necessary for me to know much about society, culture, lifestyle something like that, and I quit a job. Now I'm living in Bandung, Indonesia, and studying and feeling culture through lives of local people. - Have been surviving in Bandung, Indonesia, for studying (both Indonesian and Sundanese) culture and language with making full use of SNS (twitter, facebook, BLOG, Linkedin, CouchSurfing, etc) - Had engaged in the R&D in electronics, especially in Power Electronics (Power Conversion Circuit Topologies and Power Semi... masamukamaga.blogspot.com/ https://cdn.slidesharecdn.com/ss_thumbnails/20140117seminarukmpptmasamukamaga-140122212937-phpapp02-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/power-electronics-as-the-key-technology-for-a-better-future-20140117-maranatha-chri/30328216 Power Electronics as t... https://cdn.slidesharecdn.com/ss_thumbnails/20120731selfintroductionwebmasamukamaga-120731120753-phpapp01-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/20120731-self-introductionwebmasamukamaga-13817375/13817375 20120731 self introduc... https://cdn.slidesharecdn.com/ss_thumbnails/20120424lwaconceptmkamaga-120424022047-phpapp01-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/20120424-lwa-conceptmkamaga/12664245 20120424 lwa concept_m...
