Rectifier. In a large number of electronic circuits, we require DC voltage for operation. We can easily convert the AC voltage or AC current into DC voltage or DC current by using a device called P-N junction diode.. One of the most important applications of a P-N junction diode is the rectification of Alternating Current (AC) into Direct Current (DC).
