Abstract
This paper presents the high frequency common mode (HFCM) choke with the winding method of automatic type capable of EMI attenuation of high frequency band / used in the EMI filter of LED-TV SMPS without PFC block. The high frequency common mode choke with the winding method of automatic type proposed in this paper can not only reduce the parasitic capacitance(Cp), but also ensure the uniformity of electrical characteristics by adopting the winding methods of multi-section bobbin and automatic types, compared to the conventional high frequency common mode choke with the winding method of manual type. The first resonant frequency of the proposed CM choke tends to increase as the parasitic capacitance becomes small and its impedance characteristics improved performance as the first resonant frequency increases, especially in the high frequency bands. The high frequency common mode choke (Cp) with the winding method of automatic type proposed in this paper shows that in the future, the method may have practical use in LED/OLED-TV SMPS and in several applications, such as LED Lighting, Laptop Adapter, and so on.
