I have big issues with the ee ups core it’s getting my mosfet fire hot at 100watt I even use 1200watt mosfet push pull board I adjusted the frequency to get the right voltage and at no load the mosfet don’t get hot but a 100 watt the transformer get really warm next to hot and mosfet on fire can the core be the issue

Hello. Your multimeter has 2 keys. What are they for?

[@LongTechnical]

Thanks. Just a power switch bro

[@bahmangholami3849]

@@LongTechnical Can you teach us how to use it? It's interesting for me, but I don't know how it works.

[@debmalya6144]

Can i use a uc3845 ic instead ?

[@LongTechnical]

No bro. They are different

[@hichamtassi1753]

How many volts are in the output ? You may have to change output capacitors...

[@LongTechnical]

70 volt output. I showed in the video, checked by VOM bro

[@hichamtassi1753]

@@LongTechnical Ok thanks because usually caps in ATX are rated 16v, at 70V, they might explode.

[@LongTechnical]

Yes. I mean we reuse high volt cap. Nomally, 200V 330uF.

[@hichamtassi1753]

@@LongTechnical OK well noted, thanks.

Dear sir i need to design a power supply which is able to supply 280v

[@bm830810]

Most low power PSUs use flyback topology which their transformers have a small air gap, and are not suitable for this topology

[@LongTechnical]

This is haftbridge bro. It's stronger than flyback topology
