Abstract: An embodiment converter includes a magnetic material, a first circuit including a first winding surrounding the magnetic material and a clamp circuit configured to reset a power conversion operation, the first circuit being configured to convert power received from a first input voltage source to provide the converted power to a load, and a second circuit including a second winding surrounding the magnetic material, the second circuit being configured to convert power received from a second input voltage source to provide the converted power to the load and to perform the power conversion operation being reset by the clamp circuit.

Abstract: The present invention relates to a laminar structure which is used in a microporous layer, an electrode layer or the like of a membrane electrode assembly for a fuel cell, and also relates to a production method for same. The laminar structure is a laminar structure which is comprised in the membrane electrode assembly (MEA) of a polymer electrolyte membrane fuel cell (PEMFC), and comprises an electrosprayed layer which is formed by the lamination of electrospraying ink, that has been charged by means of an electric field, through an electrospraying process in which the electrospraying ink is dispersed and sprayed as electrospraying liquid droplets, and, in the electrospraying process, the electrospraying substance transmission mode is set in accordance with the adjustment of electrospraying process variables.

Abstract: The present invention relates to highly functional composite nanoparticles including a support body formed of nanoparticles and first phase nanoparticles which are condensed on the surfaces of the support body particles after being evaporated through a physical vapor deposition process, and to a method for producing same. According to the present invention, a physical vapor deposition process is used instead of a wet process so as to produce eco-friendly composite nanoparticles that do not emit hazardous chemicals while having high economic feasibility and process reproducibility.
