Frequent question: Which of the following can be used as voltage regulator?

Which transformer is used as voltage regulator?

One kind of transformer, an autotransformer, can be used to change voltages in a different way. In the autotransformer, the voltage is also transformed magnetically through the steel core, but there is also a direct electrical connection between the primary and secondary windings.

What is a voltage regulator?

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.

What are the types of voltage regulator?

There are two main types of voltage regulators: linear and switching. Both types regulate a system’s voltage, but linear regulators operate with low efficiency and switching regulators operate with high efficiency.

What is the most commonly used voltage regulator today?

The most common DC linear fixed voltage regulator ICs used in electronic circuits are the 78XX and 79XX series for positive and negative voltage output respectively. The XX stands for the output voltage which ranges from 2.5 V to 35 V and can support up to 2 A of current.
