Voltage regulation

Voltage regulation

In electrical engineering, particularly power engineering, voltage regulation is the ability of a system to provide near constant voltage over a wide range of load conditions. It is a dimensionless quantity defined as::VR = frac{V_{nl} - V_{fl{V_{fl imes 100%where"Vnl" is voltage at no load and "Vfl" is voltage at full load. A smaller value of "VR" is usually beneficial.

The quality of a system's voltage regulation is described by three main parameters:

Sometimes, the term voltage regulation is used to describe processes by which the quantity "VR" is reduced, especially concerning special circuits and devices for this purpose, voltage regulators. Voltage regulators are an important part of power systems and power supplies.
