Gear Wheel Method for Frequency Measurement: When a Lissajous figure contains a large number of loops, accurate counting becomes difficult. Figure 7.35 shows a test method that uses a modulated ring pattern in place of…
Gauss Seidel Method: The Gauss Seidel Method (GS) is an iterative algorithm for solving a set of non-linear algebraic equations. To start with, a solution vector is assumed, based on guidance from practical experience in…
Gate Turn Off Thyristor (GTO) - Symbol, Operations and Applications: Conventional thyristors are used as ideal switches in power electronic applications. They have the capability of blocking several thousand volts in the off-state and conducting…
Gate Function in Network Function: Gate Function in Network Function - By the use of step functions, any pulse of unit height can be realized. The pulse of width a can be generated by combining…
Gate Firing Converters: The firing pulse control unit constitutes the heart of any thyristor power conÂverter. The Gate Firing Converters required by the thyristors are often derived from the digital pulses using a simple buffer…
Gate Controlled Switch (GCS) Circuit - Operation and Advantages: As mentioned earlier, low-current drop out is the normal way in which the SCR is turned off. Gate controlled switch is designed for easy opening with…
Gate Bias Circuit: Circuit Operation - Consider the Gate Bias Circuit shown in Fig. 10-6. The FET gate terminal is connected via resistor RG to a bias voltage VG. If the gate is directly connected…
Gases and Gas Mixtures for Insulation Purposes: Over the years, considerable amount of work has been done to adopt a specific gas for practical use. Before adopting a particular gas or gas mixtures for a…
Gaseous Discharge Lamp - Working Principle and Types: Incandescent lamp suffers from two disadvantages—low efficiency and coloured light. The gaseous discharge lamp have been developed to overcome these drawbacks. The basic principle of a gaseous…
Gas Turbine Power Plant: A generating station which employs gas turbine as the prime mover for the generation of electrical energy is known as a gas turbine power plant In a gas turbine power plant,…
