Selection of Ratings of Devices of a Chopper Converter: Chopper Converter - The waveforms of currents and voltages are useful in deciding the ratings of devices. The main thyristor carries…
Two Quadrant Chopper: Sometimes a chopper may be required to provide a two quadrant operation by retaining the current direction in both motoring and braking modes. Such a Two Quadrant…
Regenerative Braking: Sometimes the energy of the load may have to be fed to the supply system. A Chopper in this mode is called regenerative. The chopper working as a…
Performance of Chopper in Steady State Condition: Assuming Steady State Condition of the chopper, we have during TON The solution of Eq. 3.89 is where Io is the current at…
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 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 midpoint converter: The converter transformer converts the existing three phase system to a six phase one, since it has six secondary windings. The Six pulse midpoint converter connections…
Two pulse mid point converter: Two pulse mid point converter are, in general, single phase converters. The pulse number of the converter indicates the frequency of the ripple voltage superimposing…
