The control of electric motor drives requires control of electric power. Power electronics have eased the concept of power control. Power electronics signifies the word power electronics and control or we can say the electronic that deal with power equipment for power control.
Power electronics based on the switching of power semiconductor devices. With the development of power semiconductor technology, the power handling capabilities and switching speed of power devices have been improved tremendously.
Power Semiconductor Devices
The first SCR was developed in late 1957. Power semiconductor devices are broadly categorized into 3 types:
1. Power diodes
2. Transistors
3. Thyristors Power diodes
