Define Voltage Regulation

Define Voltage Regulation. The ac ripple voltage that is not removed by the filters is also rejected by the voltage regulators. There are two ways to express the voltage regulation.

The lower the percentage (closer to zero), the more stable the secondary voltage and the better the regulation it will provide. As we've seen in the section above, the primary job of a voltage regulator is to drop a larger voltage to a smaller one and keep it stable, since that regulated voltage is being used to power (sensitive) electronics. It is the total opposition offered to flow of ac current in an ac circuit.

The Voltage Regulation Is Defined As The Change In The Magnitude Of Receiving And Sending Voltage Of The Transformer.


Load voltage at full load}}{\text{avg. When there is a change in the input voltage that is ac voltage of the power source the circuitry used known as a regulator which retains the constant value of voltage at the output. 7 transformer model ideal transformer 8.

Voltage Regulation Is Defined As The Change In Terminal Voltage Expressed As A Fraction Of Full Load Rated Voltage When The Load At A Given Power Factor Is Removed While Keeping The Speed And Field Current Constant.


Voltage regulation is mentioned in % (percentage). This does not mean the tolerance applies when there are sudden changes in load, it means over the permissible load range the regulation can change by this amount. The voltage regulation of an alternator is defined as the change in its terminal voltage when full load is removed, keeping field excitation and speed constant, divided by the rated terminal voltage.

A Voltage Regulator Is A Device That Maintains A Constant Dc Output Voltage Irrespective Of The Changes In Input Voltage Or Load Conditions.


The voltage regulation of an alternator is defined as "the rise in voltage at the terminals, when the load is reduced from full load rated value to zero, speed and field current remaining constant". (i) inductive reactance (ii) impedance. Thus voltage regulation can be defined as, "the drop in receiving end voltage from no load to full load expressed as percentage of receiving end voltage." for a transmission line, it is expected that receiving end and sending end voltage are same.

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.


So let's get started with concept of voltage regulation in electronics. It is the total opposition offered to flow of ac current in an ac circuit. Both values apply to the output!

It Is Commonly Used In Power Engineering To Describe The Percentage Voltage Difference Between No Load And Full Load Voltages Distribution Lines, Transmission Lines, And Transformers.
