Design And Construction Of A Power Supply Reversal Correcter Cum Preventer

The Design And Construction Of A Power Supply Reversal Correcter Cum Preventer Project Material

Overview

ABSTRACT

When power-supply polarities of an electronic device are accidentally interchanged, the device runs the risk of damage. The danger can be avoided by adding this tiny circuit to the power supply section of the device. This power supply reversal correcter circuit will instantly correct the interchanged poles of the power supply and warn of the error by raising an alarm accompanied with a visual indication.

The control element is nothing but a relay (RL1). Its supply is made unidirectional by a series-connected diode (D1). Thus in normal state the relay is idle. This arrangement is connected in reverse across the power-supply output. The output of the add-on circuit, which is taken through the normally closed contacts of the relay, via fuse F1, supplies power to the load. This way, unwanted loading of the power supply by the relay is avoided. The normally closed (N/C) contacts of relay RL1 are connected to the input terminals of the power supply in the required polarity, while the normally open (N/O) contacts are connected to the reverse-polarity terminals.
