This electronic device comprises: an electromagnetic interference (EMI) filter; a bridge diode connected to an output terminal of the EMI filter; and a power factor correction (PFC) connected to an output terminal of the bridge diode and comprising a PFC IC, wherein the PFC IC controls an inductor current, flowing in an inductor included in the PFC, so as to be maintained at or below a predetermined current value, and the predetermined current value may be smaller than the current value of the current flowing in the inductor, on the basis of a peak voltage that is applied. L'invention concerne un dispositif électronique comprenant : un filtre anti-pertubation électromagnétique (EMI) ; une diode de pont connectée à une borne de sortie du filtre EMI ; et une correction du facteur de puissance (PFC) connectée à une borne de sortie de la diode de pont et comprenant un CI de PFC, le CI de PFC commandant un courant de bobine d'induction, circulant dans une bobine d'induction incluse dans le PFC, de façon à ce qu'il soit maintenu égal ou ou inférieur à une valeur de courant prédéterminée, et la valeur de courant prédéterminée pouvant être inférieure à la valeur du courant circulant dans la bobine d'induction, sur la base d'une tension de crête qui est appliquée. 전자 장치는 EMI(electromagnetic interference) 필터, EMI 필터의 출력단에 연결된 브릿지 다이오드(bridge diode) 및 브릿지 다이오드의 출력단에 연결되며, PFC IC를 포함하는 PFC(power factor correction)를 포함하며, PFC IC는 PFC에 포함된 인덕터에 흐르는 인덕터 전류를 기설정된 전류 값 이하로 유지되도록 제어하고, 기설정된 전류 값은 인가된 피크(peak) 전압에 기초하여 인덕터에 흐르는 전류의 전류 값보다 작을 수 있다.
