It was protected all at once, but the load is poor and there is no video effect. Why is this? The circuit is unstable, 1nf and 22R are always burned, and the indicator light flashes?😢
Nice Video I think we can change output voltage range with TL431's connected resistors value right? can we make a Li-Ion battery charger adapter(for 4 S battery) with this circuit (need 16,8 volt CC MODE)
Thanks. Yes you need to change the feedback resistor for changing the output voltage but if you increase or decrease the voltage more, then you have to change the secondary turns also. You can get 16.8v but not CC
Great job KD!!! now need to make 24volt 500-800mah small smps!!! and also need to show circuit design and printing details technic full video , Thanks KD-Love U !!!
I want to make a 30 volt 10 ampere bench power supply. I did not see your current control in it. I want a circuit that can control current and voltage. Can you help me make a circuit like this? And Volt 2 to 30 wants to do that. Hope you help me.
@@Mechechao9382 it’s the auxiliary winding. It contains 6 turns and that 1 turn is just an example about the starting point and the winding direction 😊
Its a simple flyback regulator with RCD snubber, and snubber can't remove all voltage spikes, so this 500v mosfet is not the good choice it will get overheated and die soon ....... Although good video,.,.. make a video on active clamp circuit instead of rcd snubber or push pull regulator..... That will work with 500v mosfet
Could you make a video about Current and voltage adjustable power supply project? For example 0-30 volt and 0-6 amper adjustable power supply for our electronic labs
Please explain more the winding of transformer. Why are you hiding the winding part in video? Also there is no information for winding transformer in the schematic! Why? Please complete your tutorial.
This is interesting buddy, great job, I'm going to assemble it hopefully it'll work Is it a typo or what, on the list you wrote 222M as of 222 MegaOhms or?
Good job! Everything is informative except for transformer winding. Where is the end point of the second part of primary winding? Can you upload the whole video of transformer winding? Thanks and more power.
Your most welcome. You can pause the video to see the ending point. I have clearly shown it in the video. If you want to ask more about the transformer then you can message me on messenger. Thanks
Bro u r great... I was searching for this level of videos on RU-vid for many years but all youtubers are busy in playing some stupid DIYs.. There are some who are making these intermediate level videos But their numbers are very (u know). Also those are in american or British. I like ur videos but want some more explainations..
Just an order for the IC, and can you create tutorial about creating PCB and exporting for single board in EasyEDA or proteus ( preferably proteus). BTW, thanks and you got 1+ sub from Tanzania
Hello friend, I am David, one of the followers of your channel, I want to ask you a question that you should modify so that it has a 30Vdc output. thank you so much
@@MrRais66 actually the diameter of the wire is a bit less than 0.5MM and also the working frequency is between 65-75khz (depends of the tolerance of the rt resistor) so there are no problems
Hello sir, we are hobbyist in electronics, I have no formal education, basic idea from RU-vid, I have seen many of your videos, so I request you if you give me the pcb gerber file of this circuit, I would have ordered the pcb from Jlc pcb, thanks
Please reply 1 inductor specification and equivalent 2 is it possible to make it on zero pcb instead of proper pcb board Also your transformer making video is not sufficient how u did that why are u so hurry in making this video u haven't explained the circuit also it feels like you're copying someone's idea and making it for RU-vid views
HI BRO IAM IN A DO OR DIE SITUATION IN MY OFFICE ,plz help me on transformer drawing for NCP1200 100KHZ ,with PQ32/30 FOR 42V/3A U R THE ONLY HOPE FOR ME PLZZZZZZZZZZZZZZ HELP MEEE.
