A full wave center-tapped transformer rectifier ina power, Ask an Expert

Engineering

A full wave center-tapped transformer rectifier ina power supply provides an average dc output voltage of 14V onwhich a maximum ripple of ±0.5 volt is allowed. Diodeshave a 0.7 Volt drop when conducting. Assuming a resistive load of120 ohm, a line voltage of 120V rms @ 60Hz through atransformer,
(a) Sketch the circuit diagram for therectifier
(b) What is the rms voltage across the transformer secondary?
(c) Determine the size of filter capacitorrequired
(d) Assuming 50% safety margin, what diode PIV rating is appropriate?
