Question 1
A full wave rectifier uses two diodes, the internal resistance of each diode maybe assumed to be negligible. The transformer r.m.s secondary voltage is 50V and the load resistance is 1000Ω. Determine
(i) Draw and clearly label the circuit diagram
(ii) Clearly draw the output waveform of the circuit in (i)
(iii) The mean load current
(iv) The r.m.s value of load current
(v) Peak inverse voltage

Question 2
A half wave rectifier uses a transformer of turn ratio 2:1. The load resistance is 0.5??Ω. If the primary voltage is 240V. Assuming the diode to be ideal, carry out the following;
(i) Draw the circuit arrangement and output waveform
(ii) d.c output voltage and current
(iii) root mean square voltage and current
(iv) peak inverse voltage
(v) rectifier efficiency

Question 3
Draw the full wave rectifier bridge circuit diagram with 240V, 50Hz supply, transformer ratio of 8:2 supplying a load of 200Ω and assuming the diodes to be ideal. From the circuit diagram, carry out the following
(i) Draw a clearly labelled output waveform
(ii) Find the d.c output voltage and current
(iii) Find peak inverse voltage
(iv) Determine output frequency
(v) Find the efficiency if it is now assumed that the diodes have a constant internal resistance of 20Ω

Question 4
Explain the 5 advantages and 5 disadvantages of using the full wave rectifier over the half wave rectifier
