List the two advantages of Bridge Rectifier. 
by

1 Answer

Answer :

The advantages of bridge rectifier:

• The output is twice that of the center-tap circuit for the same secondary voltage.

• The PIV is one half that of the center-tap circuit.

• The need for center tapped transformer is eliminated and hence needs a simple small size transformer.

• Transformer utilization factor, in case of a bridge rectifier, is higher than that of a centre-tap rectifier.

• There is no possibility of core saturation of transformer secondary winding and hence transformer losses are reduced.

• It can be used in applications allowing floating output terminals.
