Four Quadrants Converters: Four Quadrants Converters - The converters described in the previous sections are suitable either for one quadrant or two quadrant operation. In the former case stepless speed…
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 pulse converter with freewheeling diode: A Three pulse converter with freewheeling diode across the load terminals is depicted in Fig. 3.56. The diode is meant to provide an alternative…
Bridge Rectifier Circuit Diagram with freewheeling diode: A 6 pulse Bridge Rectifier Circuit Diagram with freewheeling diode across the load terminals is shown in Fig. 3.58. As has already been…
Two pulse converters with freewheeling diode: One quadrant converters can also be obtained by connecting a free wheeling diode across the load terminals. This is possible with both midpoint and…
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…
Six Pulse Converter with Interphase Transformer: The basic connection of a Six Pulse Converter with Interphase Transformer is shown in Fig. 3.38. This is obtained by connecting two three pulse…
