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…
Types of Protective Relays: Basically, Types of Protective Relays are analogue-binary signal converters with measuring functions. The variables such as current, voltage, phase angle or frequency and derived values obtained…
Types of Electrical Drives: Types of Electrical Drives has the following major parts: load, motor, power modulator, control unit and source. There are large number of loads and each load…
DC Motor Electric Brakes: DC Motor Electric Brakes - While operating electrical drives it is often necessary to stop the motor quickly and also reverse it. In applications like cranes…
