Sample EE6501 Power System Analysis Important questions:

1. Explain the requirements of planning the operation of a power system.

Planning the operation of a power system requires load studies, fault calculations, the design of means for protecting the system against lightning and switching surges and
against short circuits, and studies of the stability of the system. (EE6501 Power System Analysis Important questions)

2. Define steady state operating condition.

A power system is said to be in a steady state operating condition, if all the measured(or calculated) physical quantities describing the operating condition of the
system can be considered constant for the purpose of analysis.

3. What is a disturbance and what are the two types of disturbances?

If a sudden change or sequence of changes occurs in one or more of the system parameters or one or more of its operating quantities, the system is said to have
undergone a disturbance from its steady state operating condition. The two types of disturbances in a power system are,
i) Large disturbance ii) Small disturbance (EE6501 Power System Analysis Important questions)

4. What is a small disturbance? Give example.

If the power system is operating in a steady state condition and it undergoes change, which can be properly analyzed by linearized versions of its dynamic and algebraic equations, a small disturbance is said to have occurred.
Example of small disturbance is a change in the gain of the automatic voltage regulator in the excitation system of a large generating unit.

5. What is a large disturbance? Give some examples.

A large disturbance is one for which the nonlinear equations describing the dynamics of the power system cannot be validly linearized for the purpose of analysis.
Examples of large disturbances are transmission system faults, sudden load changes, loss of generating units and line switching. (EE6501 Power System Analysis Important questions)

Sample EE6303 Linear Integrated Circuits and Applications Important questions:

1. What are the advantages of polysilicon gate MOSFET over aluminum gate?

The silicon film is of high quality and suitable for IC manufacturing. SOI provides a speed advantage because the source/drain to body junction capacitance is practically eliminated because the junctions extend vertically to the buried oxide. The cost of a SOI wafer is many times higher than an ordinary silicon wafer and can increase the total Fabrication cost of IC chips by ~30%.

2. What are the two common methods for obtaining integrated capacitors?

 Monolithic junction capacitor
 Thin-flim capacitor (ee6303 linear integrated circuits and applications important questions)

3. What is the purpose of oxidation process in IC fabrication?(Apr 2010)

The silicon wafers are stacked up in a quartz boat & then inserted into quartz furnace tube. The Si wafers are raised to a high temperature in the range of 950 to 1150oC & at the same time, exposed to a gas containing O2 or H2O or both.
The chemical action is Si + 2H2O ——> Si O2+ 2H2

4. What is parasitic capacitance? (Apr 2010)

In electrical circuits, parasitic capacitance is an unavoidable and usually unwanted capacitance that exists between the parts of an electronic component or circuit simply because of their proximity to each other.

5. What is meant by ion implantation?(Nov 2011, Nov 2012)

The conductivity of the semiconductor increases when small impurity is added to it. The process of adding impurity is called doping while the impurity to de added is called dopant.so ion implantation is a process of adding dopant to the silicon substrate. The ion implantation process is controllable, reproducible and also there are no unwanted side effects. (ee6303 linear integrated circuits and applications important questions)

An integrated circuit (IC) is a miniature ,low cost electronic circuit consisting of active and passive components fabricated together on a single crystal of silicon. The active components are transistors and diodes and passive components are
resistors and capacitors.

6. Increased operating speeds.

7. Reduction in power consumption

LM380 Power Amplifier
General Description
• The LM380 is a power audio amplifier for consumer application. In order to hold system cost to a minimum, gain is internally fixed at 34 dB. A unique input stage
allows inputs to be ground referenced. The output is automatically self centering to one half the supply voltage. The output is short circuit proof with internal
thermal limiting.
• The package outline is standard dual-in-line. A copper lead frame is used with the center three pins on either side comprising a heat sink. This makes the device easy to use in standard p-c layout.
