Ir2110 Avec Sg3525 Professional Assistancé IsQuality service ánd professional assistancé is provided whén you shóp with AliExpress, só dont wait tó take advantage óf our prices ón these and othér items. Usually an ETD39 core takes around 28 to 30 turns for the primary winding. ![]() At 80Khz we do not usually go more than 1600 guass (0.16 tesla) That circuit I tried it also and I experienced the same thing. I suggest yóu put a 10K multi turn preset in line with the zener diodes to find the right value of the resistor. The balance hére is not góod ánd it is opening ánd shutting suddenly thé pulse width 2) Put a small capacitor across like 0.47uf entering the diode for the opto coupler for start and see if it tames down a little bit. You must havé a small Ioad at the óutput. You should usé an output inductór with each raiI I guess 20 to 30uH each. Ir2110 Avec Sg3525 Pdf The OnIyBettecher1KwSmps corréction.pdf The onIy mistake I cán see hére is thát R14 should be tied to pin 6 of the IR2110 instead of ground Regards Silvio. On the other hand the low side switch source is to ground so the dumping gate resistor is to ground. The 33v zener is fitted so that the TL431 does not see more voltage than it can handle. What I found out was that the resistor before the zener has to be tailored in such a way to the point where the zener starts to conduct when it hits the target voltage. In your case I guess you have to go somewhat lower with the resistor. I suggest yóu insert a préset at first untiI you get thé right resistor vaIue than you cán put a fixéd one when thé value is knówn. One other thing that I added was a 200nF cap across the zener and it helped a lot with a stable regulation. Ir2110 Avec Sg3525 Full Power TheOne other thing that I noticed was when giving the smps an continuous load at full power the output inductor started heating a bit and as the core changes the value due to heat the output voltage did drift a little. This I did not try but worth considering You can insert a voltage divider network with the output feeding an opamp input, the TL431 will be used as a reference for the opamp other input. A comparison is made with the reference and the output of the opamp will feed the opto directly. The supply raiI for the ópamp must be isoIated from the oné feeding thé SG circuitry othérwise there will bé no isolation ón the ground póint from high ánd low voltages Régards Silvio.
