One of the most common uses for rectifier diodes in electronics is to convert household alternating current into direct current that can be used as an alternative to batteries. If we need a smoother output, the use of six diodes may be seen as an advantage.But the use of six diodes complicates the circuit and each diode operates for a shorter cycle.Also, since no more than six are used, the circuit is cost effective, as long as it is compared with the comparative increase in the output of the rectifier. The rectifier circuit, which is typically made from a set of cleverly interlocked diodes, converts alternating current to direct current. The following two types of rectifier circuit can be used: I.
