Why Is The Switch Of The Linear Power Supply Upside Down?

A PSU (power supply unit) or simply a power supply is a type of electrical system that is mainly responsible for the supply of electricity, also other kinds of energy, to an output load or a collection of output loads. This term is mainly used to describe a power supply that gives electrical energy.

A linear supply switch is normally upside down as an ordinary linear power supply powered by AC generally makes use of a device called as a transformer in order to perform the conversion of the voltage from the wall mains to a separate, generally lower voltage. If the linear power supply is made use of to generate DC, a rectifier circuit is made use of either as a single chip, or a series of diodes which is referred to as a diode bridge.
