Question

Task 5 Rectifiers are widely used electronic circuits in our day to day life. A laptop charger is a type of rectifier circuit. One such type of a rectifier circuit diagram is shown below: i) Complete the below circuit diagram using the suitable component symbol in the marked spaces X and Y. х R lle eletele Y ii) Name the component X and Y in the given above circuit. Write the significance of this component in this circuit. iii) Name the above circuit diagram. Describe how the above circuit working in your own words. iv) Draw the output waveform from the above rectifier circuit if an AC source of maximum voltage 12 V is connected to the primary coil of the transformer. v) Suggest and draw a rectifier circuit which is more suitable than the above circuit.

Answer 1

(i) The suitable components are Diodes + تفووووففففه Rv mu weweeeewws Y (i) X&Y Diodes significance of the diodes is, to operate. ars Swithes (iii) Name of the ciocuit is single phase center tappede Full Bridge Rectifier working → Given Supply Alternating A.C Supply > for the half cycle Dicle & X' is forward brass &'y' is in reverse bias .: x' 'X' is Ý is OFF , ON ,ie closed swith is OFF, ie open swith,

". The circuit diagram for positive half cycle is fu io ny llue بحقوقهمووووا 2 Y for negative half cycle ' is ing te verge bigs, Y is in forward Bigg x → OFF , ie openswitch Y-ON ,ie closed Switch :: The circuit for negative half cycles is x RL 2 lieu tuwelen Y (iv) output waveforma: input wore wt 217 31 Jo output ware Ver wt ग 217

N) for full wave rectifier Bridge type rectifier is more suitable because here we can avoid contar tapped TIF The Bridge rectifier circuit is Di RL * จน N D3
