For both test class D and with solid state amp will face same problem. Regarding smps output voltage, +vcc drop 40.4 and -vee increase -45.6, there is the problem. Irf740 remain cool just warm a little, 220v bridge rectifier heat raise, ntc heat raise, main trafo about 45 Celsius, mur420 heat raise, output inductor warm. With solid state amp play loud at max, 4 x 2sa1302 and 4 x 2sc3281 is hot and need bigger heatsink, best if we place fan with heatsink, when play normal about half volume temp is stable. With class D amp play loud at max, mosfet irf5 only warm about 38 Celsius with psu heatsink. Today im testing this smps with 200wrms discrete class D and solidstate with 8 output transistor (4 x 2SA1302 + 4 x 3281). Dosbox Error This Program Requires Microsoft Windows. Smps details, 2 x irf740, ir2153, run freq is 100khz, protection use current sense trafo, 4x 1n4148 + mcr100, output voltage +43.5 and -43.4, output diode mur420 x4, output inductor 25+25 laps awg 18. This smps was up and running but i have little problem when im feed it with high load. Hello today i`m build new smps with ir2153, this schematic and pcb files are from forosdeelectronica and credits go to mniclauo.

SMPS circuit SG3525 and IR2110 integrated on the board in the primer drive MOSFETs IRPF450 transformer, the. Daca nu ma insel, spuneai undeva ca nu recomanzi acest tip de condensator. of 24 - sursa cu sg3525 si IR2113 - posted in Surse de alimentare in comutatie (SMPS, Invertoare de sudura): Apropo de filtrajul high.Am gasit intr-o sursa telecom, de 1800W, punte comandata cu IR2110, folositi 10 micro/25V, tantal. I built it using the exact same parts written in the schematic. Hello everyone, I made a 50Khz SMPS using the schematic I have attached to my message. Half bridge method with different versions of the techniques used SMPS circuits test picture diagrams and photos seen in the applicationвЂ™s PCB file available control ICs TL494, SG3525 as a drive transformer and IR2110.
