- Given an input voltage of 120VAC (RMS) +/- 1% mains voltage
with 60 Hz frequency (plugged into your wall), design a rectifier
circuit that outputs +9V and -5V (account for diode voltage drop).
The output voltages should be within +/- 5% of their specification
(including peak-peak voltage ripple) with a load of up to 40 mA on
the +9V supply and 20 mA on the -5V supply. (6 points)
- Show circuit diagram of design.
- For transformer, simply specify turns ratio(s).
- Calculate no-load output voltage and max peak-peak voltage ripple for both supplies.
- Identify diode(s) part number and de-rate according to max
current and voltage.
