The following figure shows how to produce a fixed positive voltage at the output by using a fixed positive... Adjustable voltage regulator. Turn the dial or press a button on your ohm or multimeter and set it to … Attach the red wire to the input and the black wire to the ground, the multimeter should give a reading higher than the regulators' output value. This makes sure that even when a load is applied the voltage doesn’t drop. Voltage regulator, any electrical or electronic device that maintains the voltage of a power source within acceptable limits. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Updates? This article was most recently revised and updated by, https://www.britannica.com/technology/voltage-regulator. Simple voltage regulator contains a Zener Diode and a resistor but more complicated versions include elements like a voltage reference and error amplifiers. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or…. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Get exclusive access to content from our 1768 First Edition with your subscription. In motor vehicles, voltage regulators rapidly switch from one to another of three circuit states by means of a spring-loaded, double-pole switch.

Voltage regulators perform the same function in large-scale power-distribution systems as they do in motor vehicles and other machines; they minimize variations in voltage in order to protect the equipment using the electricity.

The device acts as a variable resistor, continuously adjusting to maintain a constant output voltage.

The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage. A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions. Attach the red to the ground and the black wire the output, the multimeter should then give the regulators' output value (plus minus its accuracy). We use cookies and similar tools to enhance your shopping experience, to provide our services, understand how customers use our services so we can make improvements, and display ads. Such a device is widely used in motor vehicles of all types to match the output voltage of the generator to the electrical load and to the charging requirements of the battery. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Voltage regulator, any electrical or electronic device that maintains the voltage of a power source within acceptable limits. Its accuracy to this voltage across temperature and load current is another consideration as is its maximum load. A more specific type of regulator are Low Dropout Voltage Regulators (LDO) which can regulate voltage even when the power supply voltage is very close to the supply voltage.

If not then the regulator is likely to be faulty. Types of Voltage Regulators Fixed voltage regulator. At higher speeds, resistance is inserted into the generator-field circuit so that its voltage and current are moderated. There are two types of voltage regulators: linear and switching. The primary feature in choosing a regulator is usually the Output voltage as the main purpose of one is to regulate the voltage to a specific value such as 3.3V.

Voltage regulators also are used in electronic equipment in which excessive variations in voltage would be detrimental. A voltage regulator is designed to automatically ‘regulate’ voltage level. Thus, a voltage regulator is used for two reasons:- Check the datasheet to determine which pins are the ground, input and output. Corrections? The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage. 4 Pieces Adjustable LM2596S DC-DC Buck Converter Reduced Voltage Regulator Power Module 36V 24V 12V to 5V 2A Voltage Stabilizer with Digital Voltmeter Display, BOJACK 10 Values 50 Pcs LM317 L7805 L7806 L7808 L7809 L7810 L7812 L7815 L7818 L7824 TO-220 Package High Current Positive Voltage Regulator Assortment Kit, Yizhet 5 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter Adjustable Power Supply Module, HUAREW 10 Values 50 Pcs Positive Fixed Voltage Regulator LM317T L7805 L7806 L7808 L7809 L7810 L7812 L7815 L7818 L7824 TO-220 Package IC Assortment Kit, Cocar Car DC 12V 4A Voltage Stabilizer Surge Protector Power Supply Regulator for Auto Truck Vehicle Boat Solar System etc. Sorry, there was a problem saving your cookie preferences.
