OK I choose higher rating components but coming to transformer either i need to increase secondary turns or primary turns .pls check the attached transformer details and tell me

please send me the ltspice simulation software. the above circuit is implemented by power integration please check der566

the above circuit is implemented by power integration pls check der566 file and pls explain me how the lm358 section works and i want to run the...
I designed fly back power supply 60v/3amps . circuit should be work cv and cc mode.from power integration reference circuit . actually the reference circuit is 23v/3amps . i made some changes in the circuit for 60v. and i got the constant 60v output iit is working fine. but, in the reference...
Yes my sir has told me to reduce the ringing and he compared another flyback converter in that there is no ringing coming . and one more thing is i connected a resistor 250ohms in series with transformer primary pin to line dc positive line and reduced the ringing but resistor is getting heat...
Thanku for your replay
mosfet drain to source am getting ringing . i used snubber circuit and clamp diode
also but not reducing ringing. leakage inducatance is 10mh. primary inductance is 139uh. please tell me how to reduce ringing . i will attaced the waveform pls find.
Thanks for your replay .tell me how to reduce the ringing .and what are the causes for getting the ringing. and one more thing is output voltage is not stable for 2amps load .and up to 1amps output is stable. for 2amps load topswitch ic is getting hot and output voltage goes to drop.
Hai ,
I designed flyback power supply 65v/3amps using Topswitch262EN . I got the output 65v stable . when i put the load 1amp it is ok but when i increase the load 2amps the output is going off that is thermal shutdown. i got the drain to source wave form .i am not understanding the wave...
I Externally connected the resistor 33ohms in series of AC phase for protection .in case any fault occur in the circuit components will not damage . my problem is when i switch on the supply input current going to 3amps and my Topswitch ic going to blown
Hai This is pavan .i am designing 65v/3amps flyback charger circuit with the reference circuit from PI.
when I connected the input supply through resistor (33ohms 10watt) in phase for protecting the circuit .when i switch on the supply the input current is going 3.5 amps .and resistor got very...
