Great and most sweetest lesson I ever enjoy in electronics.
Am currently having an issue working on a hybrid high frequency inverter showing error 09,after changing output mosfets,it change to 06,then I observe some zener diodes I changed off hand maybe I didn't get the real voltages,pls can u help me with real values of those zener diodes on the small output transformer...with codes zd3,7,8 .
It's 5kva/48v.

Sir you're videos are extremely helpful and I would like to thank you for that, can you make a video about :how to convert 3 phase input of VFD into Sigle phase input but the output of both are 3 phase. we only want to change the input while the output remains the same

[@mantapbetul6686]

Nice explaination. Basicly use off line transformer. DC swich only produce one direction magnetic field.

[@HaseebElectronics]

in uni-polar designs like (flyback, boost) topologies it generates unipolar magnet, and in bilpoar switching topology, then there is bilpoar magnetic flux

[@PiotrK2022]

@HaseebElectronics It's worth to also mention that it may be also a failure in the transformer winding... I'm fixing right now a Modecom ATX SMPS with both failed switching transistors,bruned fuse and desoldered one leg of subber resdistor. I fixed that problems, turned on PSU, and I notice that output voltages are very low, fo example 12V rails has 1 point sth Volt. I also noticed that snubber resitor gets very hot and after some period of time, transystors failed once again and "blew" a fuse once again...
After that failure, I inspected PSU closer and more precisely and I noticed that transfomer has sheinked nad wavy isolation. and looking from the top I also noticed that isolation layersare melted, so I removed transformer, disassembled it, what wasn't easy, because isolation tape was so badly overheated that it falls apart, so I had to scrape it peace by peace and I noticed that one of the wires in the center-tap tail is blackend partially, burned!!!!
I have 2nd PSU based on the same chassis, but with increased output power, so I borowed transformer and transistors from it, put my patient back together and bam, it worked!!!!
Transformer failed, but I have to admit that anyways it done the job perfectly, becuse isolution worked and didn't allow the sec. winding short itself with primary!!

Please explain the output section of a high frequency inverter. That is from 300 volts dc to 220 volts ac 50 Hz.
Iam getting low output voltage. Fans are running slowly. How can I increase output voltage. Please explain. 🙏

[@winstonedwards8466]

Nice info ones again ?Can a optocoupler use for the switching????

[@HaseebElectronics]

best regards and special thanks
yes optocoupler is used for switching. just set its ESR value high to drive the optocoupler in saturation
try to use TLP250, TLP350, HCPL3150 CY17 type optocouplers that is specially for isolating switching optocouplers
of use any IGBT / MOSFET driving optocouplers

[@khaiazhar8046]

Very informative video sir. You said in absence of snubber, it will cause oscillation effect. I would like to learn more on this. If you have any example video of some snubber circuit failed and cause the oscillation effect would be very helpful for me. Thank you sir.

Thank you my brother for sharing all this great knowledge really appreciate your work I have a smps that used to work from 100v to 240v AC but recently started working only at 240v can you please tell me what might be the problem why it's not working at 110v anymore thanks in advance.

Hi, I have a projector. It has pfc smps. While I check the output on a pin it shows 12 volts. But the same pin after standby release shows 17 volts. And according to instruction written on smps 17 volt is normal output voltage. How is that possible? Same pin maintaining two different voltage level!

Sir hasseb how are you ??
I have an SMPS of a sattelite receiver with IC number SD6835 have external sensor resistor 2 OHM connected in pin CS number 2
but now the resistance show 0.7ohm in multimeter
When i connect the SMPS in the motherboard of the receiver no power on and the vcc capacitor and the main capiacitor are varying
when i disconnect the smps from the motherboard i get the 5 volt .
when i reconnected to the motherboard again no power on and capacitor baby and main are varying
can you help me to r this issue ???
May i have to change the 2 external sense resistor SMD connected in parrallele ???
Number of resistor SMD 2R0
SUUPORT PLEASE
