Chopper Controlled Resistance: By interrupting the flow of current through a resistance R in a periodic fashion using a switch, the value of resistance can be effectively varied. The interrupÂtion…
Methods of Controlling Chopper Circuit: The basic principle of control of a Chopper Circuit is the effective change of the value of the time ratio. This is done in two…
Sequence control of Converters: Sequence control of Converters - We have shown that fully controlled converters take lagging reactive power from the mains. This requirement is less in half controlled…
Three phase half controlled bridge circuit: This is obtained by a series connection of a 3 pulse controlled converter and a 3 pulse uncontrolled one. The three arms of the…
Two pulse half controlled bridge converter: A Two pulse half controlled bridge converter is obtained by connecting a two pulse controlled midpoint converter in series with an uncontrolled one, as…
Phase Controlled Line Commutated Converters: In these Phase Controlled Line Commutated Converters, the commutation voltage, i.e. the voltage required to transfer current from one thyristor to the other, is provided…
