Abstract
Power cuts are a common problem. This affects industrial production and the construction of new factories and buildings. It can be bypassed by using a generator or some other form of backup power. But since it takes time to manually turn on the generator, it saves time and money. It is often observed that a single-phase fault in an electrical distribution network causes approximately 70% of outages while the other two phases operate normally. Therefore, an automatic phase selector system is required in any three-phase domestic or commercial power system to supply critical loads in the event of a phase failure. In this case, no backup power supply is required. Also, since the phase changes instantaneously within seconds, it does not take time. The main objective of this article is to give an overview of the concept of automatic phase switching for 220 to 240 VAC. However, this model is for automatic phase change (phase selector), which is designed for three-phase A.C. Input power for single phase output applications. There are many designs that perform almost the same function such as single-phase inverters, two phase automatic transfer switches and three phase automatic transfer switches.
