[0002] In daily life, switching power supplies need to use power factor correction circuits to reduce reactive power in the circuit and improve the effect of power conversion. Inductors work with other components to reduce the phase difference between the fundamental current and voltage of the AC input and improve the electrical characteristics of the circuit. SQ inductors, as common-mode inductors, can be used to suppress the electromagnetic waves generated by high-speed signal lines from radiating outward. In conventional SQ inductors, the magnetic core is installed in an upright form on the base, resulting in a high overall height. The height required on the control module also increases, affecting the use volume of the overall electronic control module, which is not conducive to use in many situations. Utility Model Content
