I have problem when I wanted design DC power supply
( I used center tap full wave rectifier with smooth capacitor and zener diode )
that problem is how I can determine ripple voltage to find capacitor value ?
I have following values
- output voltage = 4.7 V
- input voltage from transformer = 9 V . " Is it peak or RMS value ? "
-load resistance = 100 Ω.
- frequency = 60 Hz .
I asked my friend , he told me you can assume it ( ripple voltage )
but how I can assume it ?? is there certain range for assumption ??
