24 volts 10 ampere power supply

[jit_singh_tara]

hi friends ,

i would like to know that what are the requirements for making a 24 volts power supply , a step down transformer , rectifier , i am using kbpc 3510(bridge) , i want to know that capacitors to be used what value , can u suggest me something , i have a load of around 10 amperes (motor dc - 24 v)

Hi, I have checked the rectifier you use, why you are choosing KBPC 3510 but why not using KBCP 2502 (25A 200V)? The capasitor you can use is any electrolitic capasitor.I usually use the 2200 microfarad after the output from rectifier and continue with the 470 microfarad. Any value you can use for the capasitor, is to reduce the ripple that come out from the rectifier. But I recomment you use the voltageof the capasitor is higher than 25V as secure for your 10A output.

You can use very simple equation for calculating the capacitors, i.e. IT=CV, where I=current, T=time period, C=capacitors and V=Ripple Voltage. (or frequency=1/T , if you use bridge rectifier and ur input frequency is 50Hz then after bridge it is 100Hz). The power supply you intend to use is linear and power is 240W approx, if you want to use regulator then you need a very big heatsink, then I suggest a Switch Mode Power Supply.

Vripple=Idc/fc
v ripple is ur choice
i =10a
f=100
c=?
