The course describes in detail about the various firing circuits used to operate Power Electronics Devices  like SCR, 
IGBT/MOSFET. It also talks about the practically used firing circuits.

(Hindi) Firing Circuits in Power Electronics

An AC to DC Converter or commonly known as a Rectifier is a power electronic device that converts AC power to DC power. The configurations of the same are briefly classified into two - Half Wave and Full wave. Based on the control, it can be classified into two - Controlled and Uncontrolled. A Controlled Rectifier uses SCR, Power MOSFET, IGBTs, etc as switches and Uncontrolled Rectifier uses Diodes.
