Title:

CORE, TRANSFORMER, POWER CONVERSION DEVICE, AND SOLAR MODULE INCLUDING SAME POWER CONVERSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/226010

Kind Code:

A1

Abstract:

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 invention comprises: 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 length of 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.
