Analysis of low temperature effects on the performance of SEPIC in a fuel cell system

Noh M.D., Kim S., Park Y.W., Chungnam National University, KR

A single-ended primary-inductance converter (SEPIC) is to be used at the output of a direct-methanol fuel cell (DMFC) system. In this paper, SEPIC is investigated in terms of the performance variations when the operating temperature [...]

A Controller Design for SEPIC in a Fuel Cell Battery

Noh M.D., Oh O-K., Kim S., Park Y.W., Chungnam National University, KR

A single-ended primary-inductance converter (SEPIC)is a DC/DC converter that has a wide input range and is ideal for a fuel cell. The controller for a SEPIC is often designed heuristically without the consideration of the [...]

Feasibility of Wheel-Based Magnetostrictive Energy Harvester

Park Y.W., Wereley N.M., Park Y.W., Chungnam National University, KR

Manually-pushed carts with rotating wheels are easily seen around us. Also, active RFID has been gaining ground toward commercial usage. Currently possible power supply may be a rechargeable or disposable battery for the reader. The [...]

Redesign of Magnetostrictive Inkjet PrintHead

Yoon K.H., Park Y.W., Wereley N.W., Park Y.W., Chungnam National University, KR

One of the challenges is to design a proper inkjet printhead for demanding trend. Current inkjet printheads are mostly based on either piezoelectricity or heat. This paper presents an inkjet printhead using a magnetostrictive principle. [...]
