Generating Voltmeter Principle and Construction: High voltage measuring devices employ generating principle when source loading is prohibited (as with Van de Graaff generators, etc.) or when direct connection to the…
Introduction to Microprocessors and Control of Electric Drives: Introduction to Microprocessors and Control of Electric Drives - Conventionally, control of thyristor converter fed electrical drives (both dc and ac) is…
Symmetrical Optimum: Symmetrical Optimum - Sometimes automatic control systems contain integrating also besides first order delay elements, proportional elements and deadzones. Such a system when compensated on the basis of magnitude…
Closed Loop Control of DC Motor: Closed Loop Control of DC Motor - The dynamic behaviour of a system is described by a set of differential equations. On many occasions…
Introduction Control Techniques in Electric Drives: An electric drive is a well established industrial drive as it has several advantages and special features. Its Control Techniques consists in starting, speed…
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…
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…
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…
