Why do we need voltage regulator circuit in power supply?

What is the purpose of a voltage regulator in a power supply?

voltage regulator, any electrical or electronic device that maintains the voltage of a power source within acceptable limits. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage.

Why do we use a voltage regulator circuit in a power supply give any two reasons?

Every power supply in the world uses a voltage regulator to provide the desired output voltage. … Small electronic circuits rely on regulators to operate. Even the slightest fluctuation in voltage signal can damage the components of a circuit such as ICs.

What does a voltage regulator circuit do?

A voltage regulator is a circuit that creates and maintains a fixed output voltage, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other electrical components.

When should you use a voltage regulator?

The purpose of a voltage regulator is to keep the voltage in a circuit relatively close to a desired value. Voltage regulators are one of the most common electronic components, since a power supply frequently produces raw current that would otherwise damage one of the components in the circuit.

What is the purpose of voltage?

Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.

Why is voltage regulation important?

Significance of Voltage regulation

It is necessary to maintain the supply voltage of the equipment supplied by the transformer. Because the supply voltage directly affects the performance of the equipment. Hence, the voltage regulation of the transformer is significant.

Do voltage regulators waste power?

Efficiency can be calculated by dividing the output power by the input power. So if the output power is the same as the input power then efficiency is 100% and the regulator wastes no power. This is the ideal, but unattainable scenario. Most switching regulators have an efficiency between 80-90%.

How do regulators work?

Pressure regulators reduce a supply (or inlet) pressure to a lower outlet pressure and work to maintain this outlet pressure despite fluctuations in the inlet pressure. The reduction of the inlet pressure to a lower outlet pressure is the key characteristic of pressure regulators.
