Since the easily available voltage is a sinusoid, which alternates as a function of time, the first task is to convert it into a useful and reliable constant (dc) voltage for the successful operation of electronic circuits and direct current machines. The conversion process is called the rectification. Although there are other semiconductors devices suitable for rectification, diodes are frequently employed. A rectifier is a circuit that converts an ac signal into a dc signal or sometime is called ac to dc converter
