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…
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…
Phase Controlled Line Commutated Converters: In these Phase Controlled Line Commutated Converters, the commutation voltage, i.e. the voltage required to transfer current from one thyristor to the other, is provided…
Electric Converter: Electric Converter - The speed of a dc motor can be varied by varying the armature voltage or the field current, for which a variable dc supply is…
Time Delay Circuit: Several choices are available in the selection of suitable circuits for obtaining Time Delay Circuit depending on the magnitude of the time delay required. Delays of the…
Switching Transistor: The characteristics of modern Switching Transistor are specially suited to the functional requirements mentioned already. These along with the other Semiconductor production of static relays. The properties particularly…
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…
Static Relay: The term 'static relay' is generally referred to a relay incorporating solid state components like transistors, diodes, resistors, capacitors, etc. In this type of relay, the functions of…
