Demonstrates the functioning of a bridge rectifier and the principle involved in it. An integrated bridge rectifier mounted on a plastic molded case (90 x 90 x 43) mm approx. On applying AC voltage to the bridge rectifier via. 4 mm yellow sockets DC voltage is obtained via. 4 mm color coded sockets. A bridge rectifier assembly fitted on a plastic case by using four diodes, which converts AC input into DC output voltage. The block diagram of bridge rectifier printed on the top of the case.
