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. 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. 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. Also 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. In case of hybrid choke coil using rectangular copper wire, it has investigated its parasitic capacitance compared to CM choke coil of conventional toroidal type becomes small. The first resonant frequency of the proposed CM choke coil tends to increase as the parasitic capacitance becomes small and its impedance characteristics also show improved performance as the first resonant frequency increases. frequency type CM choke coil, it can be explained the parasitic capacitance of A type and section bobbin type winding methods among them is much smaller than the other. If the eMMC is parititioned and has an OS, u-boot will launch right into that.This paper presents the intra capacitance modeling according to the winding method, section bobbin and coil structure for hybrid choke coil capable of the EMI attenuation of broad bands from lower frequency bands to higher frequency bands and high frequency type common-mode choke coil capable of the EMI attenuation of high frequency band used in the EMI Block of LED-TV SMPS. If a dongle with Armbian is present in one of the USB host slots, it should boot from the dongle.īooting from USB if an OS is present on the eMMC You can use minicom on a host computer to watch the boot process and get a login screen With a clean board, it's necessary to start the board from a host computer using FEL mode. Once flashed, it's necessary to add the Recore device tree to the right folder.Ĭp sun50i-a64-recore.dtb /media/xxx/boot/dtb/allwinner/ Starting with Armbian Buster Server for Pine 64 (kernel 5.4) Xz -v -d -c Refactor-recore-v3.0. | dd of=/dev/mmcblk0Īfter that, make sure you flash the right u-boot version. Use dd to do a direct transfer of the image from the USB drive to eMMC. Get the latest ReFactor image from here: Īssuming you have managed to boot Recore from a USB flash drive and you have the ReFactor image available in the same folder, you can ReFactor Flashing ReFactor from a USB drive STM DMESH HIGH VOLTAGE MOSFET UPDATEIf you want to update that, here are the steps: Recore should come pre-flashed with ReFactor image. This document is for Revision A3, please see Recore_A2 for the previous version.
