thank you memarian..
i have calculated that site for 9-24V in put and 1A/15V output, but i have some question about that.. for ex it gives me turns ratio as 1.05(N1(prim)/N2(seconder)...so when the input 9VDC, how can be 15VDC output? at max duty of primery,the output voltage will be 8.57VDC...
Thank you Bradtherad. which program ar you using, i like this.
by the way do you have any idea about transformer sizes? there are much more kind of trasnformers.
and if i want to create my fly back circuit with 1:2 transformer, what should i use primery side as snubber circuit (parallel to...
Hi Everybody,
I need isolated dc/dc converter. Input is 9-24VDC output is 15VDC,1A. how can i design this. and what should the transformers specs be?
if you have this kind of schematics, could you share with me?(erenkcms@hotmail.com)
This is so urgent for me, if anybody can help me, i wil be...
Hi everybody,
I am using LPC1768 and i have a problem about runnin of lpc1768.
so sometimes when i open energy my board , LPC1768 doesnt run. and when i turn off and turn on board , mcu does run ( at first maybe some capacities is full and when i reset mcu ,it works correctly).
How can i solve...
ehe ehe ehe :) no welding machines :) 650A DC :).
I have a PCB and there is a uc on it.
I already do that I am sending +24VDC to switch and i regulate +24 VDC to +12 VDC with LM2575-ADJ and i am regulate +12V to +5V for uc with 7805..:)
I atteched it.
Yes you are right i want to sense switch, this switch cable is too long (more than 15 meter) and this switch cable is parallel to 650A load cable ( there are very much noises)..so if some noises comes from this cable to my PCB , my microprocessor should be locked. and when i design this PCB i...
now L3 is one core and two enductance winding on it, my purpose is that for using this core, if any noise comes from P9 to my circuit (ground or +24) L3 will block it.
so i can put diode low side(close side to PC817) as cathode to plus but i can not use diode on high side (up to P9) because all...
hmm i see, but i can not understand, why should be close? the resistor is limiting, it is no important where the resistor? am i wrong? or can you explain me why should be close?
