Design a full wave unregulated dc power supply having an input of 220 V rms 60 Hz and an output voltage maximum of 19.5 V and a minimum of 15 V. This power supply will be needed to provide power to a load which requires a maximum current of 500 mA. Assume the diode and transformer are ideal.
a. Circuit Configuration
b. Transformer winding ratio
c. Capacitor size
