Dc power supplies, Electrical Engineering

1.   Design four (4) different 5 volt DC power supplies to operate from 230 volts AC.

  • The four power supplies are to have the same full wave rectifier with capacitive filtering but are to use a different method of voltage regulation.
  • The current rating should be 0.3 Amps, with a maximum voltage variation of + 10%.

Explain the strength and weaknesses of each of the designs and why some design work better than others.

2.   Calculate the appropriate values including nominal value, power rating & voltage rating etc. for each of the components, in each of the designs. Explain why you have chosen that type and/or value.

3.   Use "MultiSim" to simulate each of the 4 circuits. Include in your report a snap shot of the waveforms after each stage in the circuit (from the input to the output) explaining the characteristics of and reason for each waveform shape.

4.   Use "MultiSim" to generate each of the schematic diagrams, and the input and the output waveforms of each circuit.
