Hi! :) I have a problem now with IR2110 (lol!). I remember someone here suggested me that I will have problems with it, there you go. My situation: I try to make HVDC to square wave full bridge AC 400Hz-1kHz inverter. I need one for a group of lamps but in future, for more heavier resistive...

Hello! I am designing a full bridge 350-55VDC SMPS (running from HVDC source). Because the IC is isolated from the source (running from a aux supply), I need a GDT. Can someone explain to me the purpose of four diodes which are connected across the IC side of transformer? Datasheet for SG3525...

Hello everyone! In net I found such smps circuit (attached). I wish to rebuild it with same parts except: - I want to make it way more powerful, at least 50W - I want to change voltage dynamically, i.e. to get a very small lab SMPS with voltage but without current limit. To test things/to...
