A voltage regulator is a kinds of electric regulator that is developed to be able to observe a level of voltage. In nearly every case it can use a unique electromechanical switch or a inactive or effective electronic component. What it uses will be dependent on what it is regulating; DC or AC voltages.
Each of the modern electrical voltage regulators - except for the inactive shunt regulators - work by comparing the output voltage that is connected to an interior stable reference voltage. The difference that is magnified and used to moderate the regulation factor is the proper way will help to shorten any kind of voltage error.
When this takes place it will form a negative feedback or servo control loop - which will step-up the accuracy of the regulation. Still, it will assist to reduce the ringing that is able to come about during definite step alterations.
If the output is at lower levels - which can be stimulated by voltage reducing or increasing the load current - the regulation component will be commanded in order to produce a higher output voltage. But this might only be done to a specific point. If the output voltage is too high then the regulation component will be commanded to make a much smaller amount of voltage.
The bulk of voltage regulators will have over current security - which will help to contain the sourcing current or to limit it. If the output current is at high levels then some regulators will mechanically close down.
