    Abstract: Disclosed are a core, a transformer, a power converting apparatus, and a photovoltaic module including the same. The core includes: a base; outer wall formed on the base; a first protruding member protruding on the base and disposed within the outer wall; and a second protruding member protruding on the base, disposed within the outer wall, and separated from the first protruding member, wherein a length of an edge of the second protruding member opposing the first protruding member is less than an outer circumference of the first protruding member. Accordingly, the second protruding member may be machined so easily that a leakage inductance can be easily controlled according to design specification.

    Abstract: A photovoltaic module includes a solar cell module including multiple solar cells, and first and second conductive lines connected respectively to first and second solar cells among the solar cells, and a junction box attached to the solar cell module. The junction box includes a power conversion unit including a capacitor unit located between the first and second conductive lines, a converter unit to change the level of a DC voltage at opposite ends of the capacitor unit and to output the DC voltage, and a controller to control the converter unit. When shading occurs in some of the solar cells, the power conversion unit supplies a second current, the level of which is lower than the level of a first current supplied before shading occurs, whereby the possibility of generation of a hot spot may be reduced despite the absence of bypass diodes when shading occurs.
