In the future, the hybrid choke coil and CM choke coil of high frequency type show it can be practically used in not only LED/LCD-TV SMPS but also several applications such as LED Lighting, Laptop Adapter, Server Power Supply and so on.Īlso it has confirmed through the experiment results that CE margin and RE margin in frequency bands 0.5MHz to 5MHz and 30MHz to 200MHz are respectively 10dB and 15dB greater than that of conventional type in case of one stage EMI filter structure adopting hybrid choke coil compared to two stage EMI Filter structure using two of each CM choke coil used in the lower and higher frequency bands or two of CM choke coil used in only the lower frequency bands. ![]() This paper presents the solution for the construction of power supplies to feed a group of coils for the new stellerator is being built in the Max-Planck Institute for Plasma Physics, IPP, in Greifswald. The 10 control coils in the stellerator are regulated by 10 power supplies, that must provide a controlled current compounded of direct current and 0–20 Hz bandwidth AC current in a range of. almost 3 kA at low voltage, 30 V, in four quadrants. Positive and negative voltage and sinusoidal current with low harmonic distortion is required by load.
