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…
Twelve pulse converter: It is clear from the preceding discussion that increasing the pulse number to six greatly improves the performance of the converter. The ac line current has only…
Six pulse bridge converter: The conduction time of a thyristor in a six pulse connection can be increased when the converter is obtained by a series or parallel connection of…
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…
Three pulse midpoint converter: These are basically three-phase converters, and are very popular because a 3-phase supply is readily available. 3-phase converters have a greater power capability than single phase…
