However, 3200W SMPS without PFC can be made, you can check DJLeco SMPS, reached 5KW without PFC. ![]() Today im testing this smps with 200wrms discrete class D and solidstate with 8 output transistor (4 x 2SA1302 4 x 3281). This smps have no feedback and its run at 50 duty cycle all the time. I think i need to short ntc with relay and add 4 more output diode with mur420 x 8. After change the inductor there is no noise at all with solid state amp. ![]() Sg3525 Ir2110 Smps Rar Programs How To Connect TwoHave you think about that Do you know how to connect two IR2153 in bridge mode Many thanks. What do you think about Sorry about my poor English Hope you understand. I successfully build a 1kw smps using the IRS2110 and SG3525. I already have a 600w smps working based on the IR2153 and IRF730 but I want to increase the power and I dont know what the better way is, if to continue use the IRF730 in bridge mode or replace for a pair of IRF460LC. Good and fast diode at output, 15 amp diode at 110 or 220 vac, 2000uf x 2 or x4 caps at high rails and auxiliary for the ir2153 u need to use external transformer to supply enough current and stable at high power or when u push smps to peak. The goal for the project is reduce the cost and use easy to find components. Ill need at least 1,5kw smps, thats why Im thinking to use in full bridge mode. Thats because Im here in order to share some info before to go to the bench. I have ordered the cores this week, maybe the next week Ill start to play. The things here in Brazil are not easy, especially when you need some parts. Is hard to find ordinary components and takes a long time waiting to come from the mail service and believe or not, are also very expensive. Thank you. If not enouh aux supply 12v to IR2153 u can hear some voice from it and seems IR2153 try to shutdown the pwm. If u wanna go for hi-power please use external aux supply for IR2153 and more caps bank at input (220 vac or 110 vac). Sg3525 Ir2110 Smps Rar Programs Driver Transformer LikeBut with IR2153 will more easy to build because IR2153 can drive mosfet directly without driver transformer like TL494. EDT49 cant go 3.2kw. Sg3525 Ir2110 Smps Rar Programs Archive High PowerFor such as power u may refer to Microsim design as he already archive high power smps.
