Power supplies are an integral part of any electrical and electronic device. These are components which supply power in terms of current with the required voltage to enable the device to function. They have an input switch through which you can set the required voltage. The switch-based power supply is widely used, especially in computers, to convert from AC to DC current. There could be a number of switch mode supplies in a single power supply unit. All of these are linked to each other, and hence shut down together when any fault occurs in the concerned electrical device. These include power supply units, adapters, switches, and more.
