Improvement in the reliability of grid-connected inverters is desirable with their increasing use. Inverter reliability tests usually focus on thermal testing of semiconductor devices. Regenerative methods are adopted to minimize the energy consumed during these tests. Regeneration requires additional systems — converters or passive components. In this paper, a novel method for thermal testing of...
This paper describes a two phase flow sensor using copper (Cu) thin film electrodes. A two phase flow constitutes a simultaneous flow of two different phases. To identify these phases in an air-water flow in a small diameter tube, Cu films were coated on to glass substrate at various substrate temperatures using dc magnetron sputtering technique. The films were characterized for their structural,...
