With the increase in electricity consumption, we will find that the voltage becomes more and more unstable, and the power of many appliances drops a lot. Therefore, in order to maintain the normal use of electrical appliances, we generally use voltage regulators. TVs also need voltage stabilizers. Next, ATO will introduce you to the relevant knowledge of TV voltage stabilizers.
Basic introduction of TV voltage stabilizer
A TV regulator is a device in electronic engineering that is designed to automatically maintain a constant voltage. A TV regulator may be a simple “feedforward” design or may contain a negative feedback control loop. TV stabilizers may also use electromechanical mechanisms or electronic modules. According to different designs, TV regulators can be divided into DC regulators and AC regulators. The 220V single phase TV stabilizer controls the stability of the output voltage. The TV voltage stabilizer may be installed in a substation or along the direction of the wire to ensure that the user can get a stable voltage regardless of the power level.
Principle of TV voltage stabilizer
Since some electrical appliances contain coil components, eddy currents that hinder the current will be generated at the initial stage of electrification. The generation of eddy currents will not only weaken the instantaneous voltage when the electrical appliances start, resulting in slow start-up, but also strengthen the instantaneous voltage generated after the circuit is broken, which may cause a spark damage circuit. At this point, a TV voltage stabilizer is needed to protect the normal operation of the circuit. The TV voltage stabilizer is composed of a voltage stabilizer circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit performs sampling, comparison, and amplification, and then drives the servo motor to rotate, so that the position of the voltage stabilizer carbon brush changes, by automatically adjusting the coil turns ratio, so as to maintain the stability of the output voltage. The TV voltage stabilizer with a larger capacity also works on the principle of voltage compensation.
Function of TV voltage stabilizer
A TV voltage stabilizer is a power supply circuit or power supply equipment that can automatically adjust the output voltage. This circuit or electrical equipment can work normally under the rated working voltage. All TV regulators use the same technology to stabilize the output voltage. The output voltage is sampled by a voltage divider resistor connected to the inverting input of the error amplifier, which is connected to a reference voltage.
