Common Gate Circuit: The FET Common Gate Circuit (CG) shown in Fig. 11-19 uses voltage divider bias. The ac output is taken from the drain terminal, and an external load (RL) is capacitor-coupled to the…
Effects of Harmonics: The relationship between line and phase quantities for wye and delta connections as derived earlier are strictly valid only if the source voltage is purely sinusoidal. Such a waveform is an ideal…
Methods of Controlling Chopper Circuit: The basic principle of control of a Chopper Circuit is the effective change of the value of the time ratio. This is done in two ways: 1.Time ratio control 2.Current…
Load Commutated Inverter Fed Synchronous Motor Drive: Load Commutated Inverter Fed Synchronous Motor Drive is shown in Fig. 10.22. The inverter is a current source inverter employing thyristors T1 - T6. The commutation of inverter thyristor is…
IC Packaging Process | IC Package Types: After completing all the fabrication processes, several chips are ready on a wafer. Each of the chip is nothing but a complete circuit. Now the next step is…
Grading of Cables: The process of achieving uniform electrostatic stress in the dielectric of cables is known as grading of cables. It has already been shown that electrostatic stress in a single core cable has…
OTA as Programmable Resistor, Grounded Resistor and Floating Resistor: OTA as a Programmable Resistor: We may employ Ic OTA as a programmable resistor whose resistance is controlled by controlling current Ic. We can define resistance,…
Speed Control and Drive Classification: Speed Control and Drive Classification are the Drivers where the driving motor runs at a nearly fixed speed are known as Constant Speed or Single Speed Drives. Multi-speed drives are…
Limitations for Loading Capability of Transmission System: There are three kinds of limitations for loading capability of transmission system: Thermal Dielectric Stability Thermal capability of an overhead line is a function of the ambient temperature,…
Self Controlled Synchronous Motor Drive Employing a Cycloconverter: Self Controlled Synchronous Motor Drive Employing a Cycloconverter as shown in Fig. 7.13. Firing pulses are generated either by comparison of the motor terminal voltages or by…
