mr_sotong SG how to get the capacitance if given: Vpri = 220v 50Khz Vsec = 44v 0.5%ripple RL-1kohms Isurge(max) = 1A DC output voltage = 15v
eagle SG because the labels are so short Vpri Vsec RL etc... We won't know what it stands for, nor what topic is it from.
Darkness_hacker99 SG For the past few nights, I have been searching the net hopping something would shed light on this question.. Hmm~ Still can't find it leh. This question is it related to transformers anot?
eagle SG not enough information was given and now we are told it is a step down transformer after 11 posts Any more information missing? Let me guess Vpri is AC Vsec is AC Output voltage is DC (15V) Rectifier circuit was used in conversion from AC to DC, and hence the ripple
eagle SG In addition, the circuit on the secondary side can thus be seen as shown: The capacitance in the diagram is what you need to find right?
mr_sotong SG but but but its already very obvious since i already stated that Vpri is 220v and Vsec is 44v..
Darkness_hacker99 SG I read that the main current is determined by the turn ratio. which is Vpri/Vsec = 220/44 = 5.
eagle SG that part is obvious the circuit is not btw, the circuit posted above is still missing something. I still fail to see why Vsec is 44V while Voutput is 15V
