Description
The evolution power supply 3-phase is a type of transformer . It converts three-phase alternating current into single-phase alternating current. The primary windings are excited by three-phase voltage source. The output voltage is the average of the input voltages. It can be used when the output of a generator or an inverter is three-phase, or when the load includes motors which need to be started on single phase.
The major uses for this device are in electric lighting, power transmission and distribution, and traction systems. In modern times, it is not commonly used for electric lighting as incandescent lamps have been replaced by more efficient alternatives such as fluorescent lamps, LEDs and HIDs. This has resulted in a sharp decline in the demand for transformers and inverters. However, they are still used in traction systems to convert the direct current produced by diesel engines into alternating current required by the electric motors that propel trains, trams and trolleybuses.
This device consists of two identical coils wound on separate laminated magnetic cores. Each core has two sets of teeth on its opposite sides so that the teeth from one set intermesh with those from another set at right angles, which produces high mutual inductance between them.
