What is meant by voltage regulation?
In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission or distribution line.
What is voltage regulation of a transmission line?
Voltage regulation of transmission line is defined as the ratio of difference between sending and receiving end voltage to receiving end voltage of a transmission line between conditions of no load and full load. It is also expressed in percentage.
What is voltage regulation and its significance?
Voltage regulation is the measure of how well a power transformer can maintain constant secondary voltage given a constant primary voltage and wide variance in load current. The lower the percentage (closer to zero), the more stable the secondary voltage and the better the regulation it will provide.
How is threshold voltage related to flatband voltage?
The threshold voltage equals the sum of the flatband voltage, twice the bulk potential and the voltage across the oxide due to the depletion layer charge, or: where the flatband voltage, VFB, is given by:
Which is the correct definition of voltage regulation?
Electrical power systems. In electrical power systems, voltage regulation is a dimensionless quantity defined at the receiving end of a transmission line as: where V nl is voltage at no load and V fl is voltage at full load.
How is the threshold difference due to an applied bulk voltage expressed?
The threshold difference due to an applied source-bulk voltage can therefore be expressed by: Where g is the body effect parameter given by: The variation of the threshold voltage with the applied bulk-to-source voltage can be observed by plotting the transfer curve for different bulk-to-source voltages.
How does the back contact affect the threshold voltage?
The voltage applied to the back contact affects the threshold voltage of a MOSFET. The voltage difference between the source and the bulk, VBS changes the width of the depletion layer and therefore also the voltage across the oxide due to the change of the charge in the depletion region.
