Chopper Controlled Resistance

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 interrupĀ­tion of the current can be accomplished by means of a dc chopper connected across the resistance, working as a switching device. When the chopper is […]

Sequence control of Converters

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 converters and converters with a freewheeling diode, which however do not provide the process of inversion. In both cases the reactive power requirement increases as […]
