semiconductor

A electric circut which convert AC voltage into a DC voltage

1. One diode

2. + s1 w.r s2

3. Forward baised

4. - s1 w.r s2

5. Reverse rectifier

A full wave rectifier circuit uses two diodes.

D1 conducts in the positive half cycle and D2 conducts in the negative half cycle of the input voltage.

During the positive half cycle of the input voltage, the point A is at a higher potential than that of the point B and the diode D1, conducts.

During the negative half cycle of the input voltage, the point B is at a higher potential than that of the point A and the diode D2, conducts.

1. 2 diode

2. D1 = + , D2 = -

3. + , A higher point than b

4. - , B higher than A

Rectification takes place in both the cycles of the AC input.

Ripple in Full wave rectifier is less than half wave rectifier

A filter circuit used to remove ripple from the output of rectification
