  1. Am renuntat la autooscilanta si am folosit chipul ICE2QS03G, nu a explodat nimic inca, nu se inchinge nimic, dar pe auxiliar primesc mereu 6.7V, si nu am idee dece, are cineva vreo idee ce poate cauza asta ?
  2. Am banuit lucrul acesta si am incercat cu o rezistanta de 1R 1W (nu am de 0.22) si a explodat..
  3. Buna ziua, incerc sa reproduc aceasta sursa in comutatie, schema la url http://danyk.cz/impulz3_en.html si am intampinat o problema. Nu merge :D Au fost folosite urmatoarele componente: Transformatorul MYRRA 74087 link: https://www.tme.eu/ro/details/74087/transformatoare-pcb/myrra/ Tranzistorul de putere STP10NK60ZFP link: https://www.tme.eu/ro/details/stp10nk60zfp/tranzistori-canal-n-tht/stmicroelectronics/ si IRF840SPBF link https://www.tme.eu/ro/details/irf840spbf/tranzistori-canal-n-smd/vishay/ in ambele cazuri se supra incalzeste foarte tarea si nu imi da nicio tensiune la iesire. Dioda zener 1N5353B (16V) In locul tranzistorului KC507 am folosit BC547A In locul condesatorului de 2.2n am 3.3n Rezistenta 0R22 am presupus ca e 22R 1W, asa e? NTC de 5ohm la 25C Si in final optocuplor am folosit VOS615A-3X001T link https://www.tme.eu/ro/details/vos615a-3x001t/optocuploare-iesire-analogica/vishay/ Prin urmare, nu explodeaza nimic, nu pica siguranta ci se incalzeste incredibil mosfetul. Atasez o poza, sper sa ajute, restul link : https://photos.app.goo.gl/TC1KXDzZrHsMgEdw6 .
