Hi
I second Renovator1's comment about getting a higher rated voltage MOSFET than you appear to need.....I once built a 24V 2A offline flyback (discontinuous mode) and the DC bus was 320V. On MOSFET turn-off, the voltage across the MOSFET spiked up to 1400V. (Even with the secondary referred...
another problem to watch is the reflected voltage from the secondary back to the primary (ie referring to discontinuous mode, when the switch is off)....your secondary spans 24+15 = 39 volts.......when the switch is off this will be reflected back to the primary.....and if you have say , turns...
Hello
I have been given some orders for various electronics. (LED displays, intercoms etc) I am living in Hayes,London, UK and wish to locate an electronics hardware shop that sells IC’s, transistors etc. I doubt I will be able to order from RS as I am not a public listed company.
I am...
Hi,
With an 800KW fan i'd be surprised if the fan supplier did not have some ideas for you so its worth trying them.
If its supplied from some sort of VSD then you could maybe code in some kind of soft start.
Alternatively, switching out resistors just after start-up as you say sounds good.
