What does voltage regulator do?
What does voltage regulator do?
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.
Is voltage regulator part of alternator?
The main component in the charging system is the ALTERNATOR. A VOLTAGE REGULATOR regulates the charging voltage that the alternator produces, keeping it between 13.5 and 14.5 volts to protect the electrical components throughout the vehicle.
Where can I find a voltage regulator for my car?
There are 14 references cited in this article, which can be found at the bottom of the page. Voltage regulators are commonly found in vehicles and other electronic equipment. A voltage regulator will limit the maximum amount of voltage from a power source and prevents a device or alternator from shorting and overheating.
What kind of voltage does a voltage regulator regulate?
Any type of electronic device that plugs into a wall outlet has a voltage regulator in it. The regulator regulates the voltage from 120V AC to 12V DC, or whatever voltage is required by the circuit. Thanks! Make sure you know how to use a multimeter properly before attempting to do so.
How does voltage regulation circuitry located within a PCM control the?
On modern vehicles, voltage regulation is the responsibility of the powertrain control module (PCM). There is no need for a separate regulator. In most cases, the PCM monitors battery voltage, engine speed and battery temperature. It then pulses the alternator’s field coil to control output. Click to see full answer.
How does a linear regulator work and how does it work?
Linear regulators work like a variable resistor with feedback, dropping any unneeded voltage. While drawing the same current as the load. This wasted energy is converted to heat, making these regulators hot and inefficient at high currents.
What is voltage regulator and how does it work?
A voltage regulator is basically a beefed up emitter follower, like described above – a transistor connected to a stable reference that spits out a constant voltage, dropping the rest. They also have a built in error amplifier, which samples the output voltage (again through a divider), compares it with the reference voltage, calculates the difference, and drives the output transistor accordingly.
What is a constant voltage regulator?
A voltage regulator is a system designed to automatically maintain a constant voltage level. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.
What is an AC regulator?
AC voltage stabilization refers to the regulation of relatively minor fluctuations in AC voltage. These voltage regulators are routinely used in a home to keep the voltage within the range needed by household appliances.
What is voltage regulation?
Voltage regulation. In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission or distribution line.
