Hi, I am currently designing a Power supply with a transformer 220V to 30VAC then using a full bridge rectifier (10A).
The peak DC voltage (after adding 4700uF with no load) is 30 x 1.414= 42.4V
I am using two LM338 voltage regulators to step down the voltage to 36Volts.
The required capacitor to reduce the ripple (Vpp) is around 50,000 uF?? this should tie the Vpp to 1.2 Volts @50Hz, 6Ampere load
My problem is that I cant find any giant capacitors to reach 50,000uF with rated voltage 50V
Are there any solutions to that case?
What would be an acceptable Vpp voltage that wouldn't heat up my regulators and maintain my required regulated voltage?
