Power Electroincs in Electrical

Power Electronics : In older we used mechanical devices for most of the process. Like, to turn of the circuit we need separate mechanical switch. The same case for all the things. Now the trend is changed. The introduction of Power electronic devices make this process easier. In former cases, there are so many losses due to this mechanical movement.
But in his later Edison, what ever may be circuit size we can operate with minimum power. It is so efficient and occupies less space. Due to this devices, all electrical equipment size getting reduced.Cost of this device is also low compare to other mechanical equipments. Power electronics is the emerging field, where all the power engineering equipments are controlled by this simple devices. There are many improvements in this devices so that it can operate automatically without external operator. This will be discussed later.
