Thyristor means is a 4 layer device with two terminals ,
the anode and the cathode. The main diff is the silicon
controlled rectifier.
The diac means it has two terminals A1 , A2. It conduction
occurs in a diac when the breakover voltage is reached with
either polarity across the two terminals.
The triac is like a diac with a gate terminal it's mean
three terminals. A triac can be turned on by a pulse of
gate current and does not require the breakover voltage to
initiate conduction.

what is the series parallel connection of capacitors? and how can we use these application in three phase motors for controlling torque?
