Basics of Power electronics Power Electonics is the subject that deals with convert or control the power(AC or DC).The devices which are used to control power the are called "power controlling devices".there are may number such devices are designed for the purpose of controlling the power.All such devices are thyristor family devices[1].Some of the Thyristor devices are SCR,DIAC,TRIAC,GTO SCR,LASCR,SUS,SBS,SCS,Power MOSFET,IGBT etc. SCR is the basic device among all thyristor family devices.
the symbol and volt-ampere characteristics are shown below.
