Explain the requirement of the redundant power supply
It’s a Diode coupler. which is used when two independent power supplies used in redundant mode. Benefits suppose one power supply failed voltage does not come to reverse and avoid voltage drop. It is a redundant module that takes two input power supply (D c) and gives single output DC supply. Diode Oring unit used for DC power supply from two independent DC power source.
A redundancy module with protective coating can be used as a parallel connection of two power supply units that are decoupled from one another. It’s a module which use for decouple two power supplies of same type. In the event of an internal fault of one device, the other device automatically takes over the complete power supply without interruption and vice versa…
What is the redundancy of power?
Power redundancy, therefore, refers to duplicated or back up power facilities in a system or infrastructure for power continuity.
Why is a diode used in a DC power supply?
When a diode is inserted along the path, the reverse motor current has path to follow and the reverse voltage is limited to that equal to the forward voltage drop of the diode.
This helps shield the power supply’s output capacitors and any other component in it that might have been Fried by reverse voltage.
