It is required to use a full wave peak bridge rectifier to design a DC power supply that provides an average DC output voltage of 15 V on which a maximum of +/- 1 V ripple is allowed. The rectifier feeds a load of 150 Ω. The rectifier is fed from the line voltage (120 V rms, 60 Hz) through a transformer. The diodes have a 0.7 V drop when conducting (at all currents).
a) Specify the rms voltage that must appear across the transformer secondary.
b) Find the required value of the filter capacitor.
Draw waves and circuits.
