I have designed adjustable output voltage and curent SMPS having 500W output. I would like to share circuit schematic since there are many experienced people in SMPS and power electronics in this forum. Do you have any suggestion about this circuit ? or Do you see any critical fault ? This...
Hi everyone. I have designed 2kW SMPS for my friend but i am stuck in designing feedback voltage regulation for -70V. I saw a circuit that it was sharing the feedback currents for dual rails. I have also read in book and it says the aim is to share feedback currents. I did it but i dont know...
Hi guys, i have designed 2kW SMPS. Could you pls tell me whether this circuit has fault or not ? You can also give some advice to make it better. Thnx.
Here is the OrCAD results;
Actually i do not know how to calculate feedback network accurately. I am really confused that which book is good for calculating. Since I've used marty brown's power supply cookbook, presmann's switching power supply design and basso's book. Pressmann's book does...
I've simulated my full bridge circuit via Psim but i cannot get a stable 370VDC at output. I calculated my feedback network according to Switching power supply design and Power supply cookbook. I've also used Basso's book. When i set the input voltage to lower value, output also goes down, and...
Hi everyone i am newbie in SMPS design. I really wonder how you complete the feedback compensation network in SMPS. I know the type 1, 2 and 3 but i cant design it completely for SMPS. Whats the best way to design feedback compensation network ?
