So, scheme from message #44 does not be fit?only regrets no protection
yes, of course. Possible even use simply 15W resistor like that as it is written in datasheet (with external 15V zener on ir2153 Vcc).can i use 15v seprate supply for 2153?
no, yellow cores is only for DC. For high freq. AC it is need ferrite cores like №87 material.yellow core from pc supply OD22MM ID 14 MM H 7MM is it ok to use
it is not my smps, only my version of this. )detex audio say your smps is good
Well, probably this signifies that optotransistor is open or perforated. To understand why it is possible to walk on scheme with voltmeter. Of course it is necessary disconnect power part from +310VDC for time of the testing. Apropos better use thyristor (like bt136) instead of TL431. Since if thyristor is opened that is latched.TL431 and opto 817 smps does not come on
about this me not known nothing ).when i use 555 ocp smps comes on but ocp not working
