The mechanism of a Voltage Regulator

The mechanism of a Voltage Regulator

A voltage regulator can be referred to as an electronic device that is used to regulate one or multiple AC or DC voltages. When there is a requirement of a strong and reliable voltage, then a voltage regulator works as an ideal device. It creates a stable output that remains constant even if there is any change in the load conditions. It acts as a shield that is meant to protect the components from any severe damages.

Features of a voltage regulator Depending on the mechanism, a good voltage regulator is comprised of salient features. Let us have a look.

Types of Voltage Regulators There are two types of voltage regulators i.e. Switching voltage regulators and Linear voltage regulators.

The linear voltage regulators are considered as the simplest type of voltage regulators. It has two main types. The switching voltage regulators are used in wider applications. Let us have a quick discussion about different types of regulators.

Linear Regulator- Series and Shunt The Linear regulator works as a voltage divider. The overall resistance of the voltage regulator changes with the load resulting in the constant output voltage.

• It has a fast response time to line or load changes • It gives a low short output ripple voltage • Less noise and low electromagnetic interference Series Voltage Regulator A series regulator uses a changeable element which is placed in a series with a load. When there is a change in the resistance of the series element, the voltage which is dropped across can be easily changed. The voltage across the load remains quite constant. The main advantage of the series voltage regulator is that the drawn current is used by the load quite effectively.

Shunt Voltage regulator A shunt voltage regulator provides a path from the supply voltage to the earth by using the variable resistance. The current which is present on the shunt regulator diverts away from the load and uselessly flow on the ground. This regulator usually absorbs a huge amount of current.

Where is shunt regulators used?

There are multiple things in which the shunt voltage regulators are used.

• • • • •

Error amplifiers Precision current limiters Sink circuits and the current source Switching power supplies with a low output voltage Voltage monitoring

Switching Voltage Regulator A switching regulator continuously switches a device on and off. These regulators are meant to generate the output voltages that are higher than the input voltage.
