The present invention relates to a core, a transformer, a power conversion device, and a solar module including the power conversion device. A core according to an embodiment of the present inventioncomprises: a base; an outer wall formed on the base; a first protrusion member protruding from the upper surface of the base and positioned in the inner space defined by the outer wall; and a second protrusion member protruding from the upper surface of the base and positioned in the inner space defined by the outer wall while being spaced apart from the first protrusion member, wherein the lengthof the edge of the second protrusion member, facing the first protrusion member, is shorter than the outer circumference of the first protrusion member. Accordingly, the second protrusion member is easy to process, and thus leakage inductance can be easily adjusted according to design specifications.
Description
technical field [0001] The present disclosure relates to a core, a transformer, a power conversion device, and a photovoltaic module including the power conversion device, particularly to a core that can be easily machined so that the leakage inductance can be easily controlled according to design specifications, and to a transformer, a power conversion device, and a photovoltaic module including the same. Photovoltaic modules for power conversion devices. Background technique [0002] A power conversion device adapted to produce a photovoltaic module or the like of reusable energy to provide AC power (AC) or the like. [0003] In particular, transformers, leakage inductors, etc. are used in converters to convert DC power (DC) generated by photovoltaic modules and the like. [0004] Meanwhile, in the case where the winding space of the transformer is divided into an upper area and a lower area, an air gap is arranged in the middle between the upper area and the lower area. ...
