For RC snubbers,5R6/2W and 330 pf/500v as a starting point, what do you think?
hi sir i want to know that in 1kv smps based on microsim design using ir 2110& sg3525 &etd 49 core the wattage is 1kv. if i change the mosfet irfp460 to igdt g4pc50u the supply can go to how many watts.should it will remain the same or the wattage will increase so tell me its max watt using igbt g4pc50uwhile replacing the old rectifier with the larger one, the pcb got a little bigger, but that will be corrected. also the current sense lines are a piece of cable (like ludo's prototype), thinking about moving the ne555 from the protection circuit a little higher (then you have to use cable). have to add the ultra-fast diodes and caps, and move the ETD core more to the right. if you spot some mistakes, please say right away.
Hi.
I try to choose the snubber.I do not know how to choose the resistors.
course without capacitor, Dren/Source Q1 (osciloskope 10V/plot,probe 10X)
I used a capacitor 4,7nF
I bought a new digital oscilloscope. Now I will do a professional measurements.
