POWER SUPPLY
in [Design]
|
From: Jimbo on 27 Feb 2006 05:20 I'm designing a power supply which uses a transformer, Full wave bridge rectifier, capacitor and an inductor. Is there any reason why I should use an inductor and a capacitor rather than just a capacitor. Jimmy

From: Reg Edwards on 27 Feb 2006 06:41 Using an inductor will give better output voltage regulation versus load current. If you have a constant load current then don't bother with the inductor. For given ripple volts across the capacitor, if you don't use an inductor then you will need a much bigger capacitor. If all you want is rectified AC then don't bother with either. ---- Reg.
