Half Wave and Full Wave Rectifier

In Half Wave Rectifier, when AC supply is applied at the input, positive half cycle appears across the load, whereas the negative half cycle is suppressed. This can be done by using the semiconductor PN – junction diode. The diode allows the current to flow only in one direction. Thus, convert the AC voltage into DC voltage.

In Full Wave Rectification, when the AC supply is applied at the input, during both the half cycles (i.e., positive as well as negative) current flows through the load in the same direction. This can be achieved by using two crystal diodes. The two diodes conduct the current alternately.

Answer 2

⭐ In the positive half cycle o AC there is a current through the load resistor , and we get the output voltage where as there is no current in the negative half cycle .

In the next positive half cycle , again we got the output voltage . Thus the output voltage is restricted to only ine direction and the rectified output of this circuit is only for half of the input AC wave ,

It is a half wave rectifier .

⭐The circuits using two diodes gives output rectified voltage corresponding to both the positive as well as negative half of the AC cycle , Hence

It is a full wave rectifier .
