Any electrically run device works under the basic factors of current (I), volt (V), and resistance (R). All three given variables are interconnected to each other and are the basic factors responsible for the efficient running of any particular electronic device. To regulate the voltage flow across a circuit, certain complementary devices are installed. A Voltage regulator is a specially designed extra device in the circuit that regulates the level of voltage automatically.
To simplify, the mechanism adopted by a voltage regulator helps the circuit to which the device is connected to step up or down as per the desired level of the input voltage. The mechanism of a voltage regulator also bears testament to the fact that during the supply of current, the particular voltage regulator helps to maintain the level of voltage as constant. The voltage regulator also ensures that even in a situation of extra input of load, the constant level of voltage does not drop. The overall usability of voltage regulators indicates that it helps to maintain the flow of the circuit in any given condition.
The voltage regulator has its use and utility in a variety of fields, devices, and circuits. The uses of voltage regulator are listed as follows:
- It regulates the varying level of output voltage in the circuits.
- In spite of variations in supply voltage or the supply of load in current, the output voltage remains constant at the desired level.
The application of voltage regulator lies in computers, alternators, power generator plants in which the output of the plant is controlled in the circuit by the voltage regulator. There are different types of voltage regulators which run under AC source and DC regulators.
The voltage regulator maintains a regular level of voltage in different fields. Every field has a different kind of impact on the flow in a circuit which in turn affects the functioning of the device. To ensure the voltage regulator works with consistency, a high voltage divider is used. A voltage divider is a circuit that is fundamental to the functioning of devices.
A high-frequency voltage divider is responsible for converting the large voltage into smaller units. The circuit involves the use of a series of two resistors and an input voltage of preferably high value. The output voltage is as low as the fraction of the voltage input. A high-frequency voltage divider is a kind of circuit that works for both high and low-frequency signals or voltage levels.
A voltage regulator is the same as a number of variable resistors. It helps to regulate the swinging value of output voltage. The only limitation related to the voltage regulator is that there is the presence of a response time such that the output voltage can swing or jump in and around the fixed value. In these cases, a capacitor is used. A capacitor is a storage device that stores energy and thus the voltage present in the capacitor does not have the ability to change almost instantaneously. So if you want to get a smooth change, a capacitor is an absolute must.
