I believe everyone does not know much about the stabilizer, but it plays a great role in our home.It can automatically adjust the power supply equipment of the output voltage, so that the fluctuating unstable unstable power supply voltage stabilizes within the corresponding range, so that various circuits electrical equipment, etc.The topics of this issue will be explained in detail for everyone.
What is a regulator
The stabilizer is a device that stabilizes the output voltage.The voltage regulator consists of pressure regulating circuit, control circuit, and servo motor.When the input voltage or load changes, the control circuit is sampled, compared, and enlarged, and then drives the servo motor to rotate to change the position of the pressure regulator carbon brush. By automatically adjust the number of coil turns, keep the output voltage stable.
The role of the stabilizer
The voltage regulator is a power supply circuit or power supply equipment that can automatically adjust the output voltage. Its role is to stabilize the voltage of the power supply that fluctuates large and not to meet the requirements of the electrical equipment.The equipment can work normally under the rated work voltage.
The initial power regulator relied on the jumping stable voltage of the relay.When the power grid voltage fluctuates, the automatic correction circuit of the power voltage regulator is started to make the internal relay movement.
Forced the output voltage near the set value. The advantage of this circuit is that the circuit is simple, the disadvantage is that the voltage voltage accuracy is not high and each relay beating shifting will cause a instantaneous interruption of the power supply supply and spark interference.
This is very disturbing to the reading and writing of computer equipment, which is easy to cause an error signal of the computer. In severe cases, it will also damage the hard disk.
Most of the high -quality small voltage regulators are mostly used to stabilize the voltage of motor carbon brushes. This voltage regulator has a relatively high voltage voltage accuracy of electrical equipment.
The working principle of the stabilizer
Because some electrical appliances contain coil components, the vortex that hinders current will be generated in the early days of power. The generation of eddy current will weaken the instantaneous voltage when the electrical appliance starts, resulting in slow starting, and the instantaneous voltage generated after the road is disconnected. It may cause spark damage.Circuit.At this time, a regulator is needed to protect the normal operation of the circuit.
The voltage regulator consists of pressure regulating circuit, control circuit, and servo motor. When the input voltage or load change, the control circuit is sampling, compared, and enlarged, and then drives the servo motor to rotate to change the position of the carbon brush of the regulator.By automatic adjustment of the number of coil turns to keep the output voltage stability.A large volume voltage regulator also uses the principle of voltage compensation.
