A transformer core having an advantageous shape in terms of processing is disclosed. The present invention provides a transformer core, a power conversion apparatus including the transformer core, and a photovoltaic module including the power conversion apparatus. The transformer core includes a body having an inner wall, an intermediate wall, and an outer wall formed from the center thereof, with a first wire wound between the inner wall and the intermediate wall, and a second wire wound between the intermediate wall and the outer wall, wherein the body includes: a first body in which a portion of the inner wall and the outer wall are formed protruding from a base; and a second body in which a remaining portion of the intermediate wall and the outer wall are formed protruding from the base, wherein the second body is coupled to the first body to be overlapped thereby. Un noyau de transformateur présentant une forme avantageuse en termes de traitement est divulgué. La présente invention propose un noyau de transformateur, un appareil de conversion de puissance comprenant le noyau de transformateur, et un module photovoltaïque comprenant l'appareil de conversion de puissance. Le noyau de transformateur comprend un corps comportant une paroi interne, une paroi intermédiaire et une paroi externe formée à partir de son centre, avec un premier fil enroulé entre la paroi interne et la paroi intermédiaire, et un second fil enroulé entre la paroi intermédiaire et la paroi externe, le corps comprenant : un premier corps dans lequel une partie de la paroi interne et la paroi externe sont formées en saillie à partir d'une base ; et un second corps dans lequel une partie restante de la paroi intermédiaire et la paroi externe sont formées en saillie à partir de la base, le second corps étant couplé au premier corps pour être chevauché par celui-ci. 가공 측면에서 유리한 형상을 가지는 변압기 코어가 개시된다. 본 발명은 중앙으로부터 내벽, 중간벽, 그리고 외벽이 형성되고, 상기 내벽과 중간벽 사이에는 제1 와이어가 감기고, 상기 중간벽과 외벽 사이에는 제2 와이어가 감긴 형태의 몸체를 포함하는 변압기 코어로서, 베이스로부터 돌출된 상기 내벽과 상기 외벽의 일부가 형성된 제1 몸체; 및 베이스로부터 돌출된 상기 중간벽과 상기 외벽의 나머지 일부가 형성되고, 상기 제1 몸체에 포개지도록 결합된 제2 몸체;를 포함하는, 변압기 코어, 변압기 코어를 포함하는 전력변환장치 및 이를 포함하는 태양광 모듈을 제공한다.
