(1) Ferromagnetic resonant communication regulator: a communication regulator composed of a full choke and a corresponding capacitor, with constant voltage voltammetry characteristics. The full type is a typical structure in the early stage of this type of regulator. It has the advantages of simple structure, convenient production, wide allowable scale of input voltage, reliable operation and strong overload capacity. However, the waveform distortion is large, and the stability is not high. Recently developed voltage regulators are power supply devices that regulate voltage by means of nonlinearity of electromagnetic components. It is different from the magnetic full voltage regulator in the form of magnetic circuit structure, and the fundamental operating principle is the same. It completes the two functions of voltage stabilization and voltage transformation on a single core, so it is superior to general power transformers and magnetic full conditioners.
(2) Magnetic amplifier communication voltage regulator: a device that connects a magnetic amplifier and an autotransformer in series, and changes the impedance of the magnetic amplifier through an electronic circuit to stabilize the output voltage. The circuit form can be linear amplification or pulse width modulation. This type of regulator has a closed-loop system with feedback control, so it has high stability and good output waveform. However, due to the large inertia of the magnetic amplifier, the recovery time is long. Because of the self-coupling method, the anti-disturbance ability is poor.
(3) Sliding communication voltage regulator: a device that changes the orientation of the sliding contact of the transformer to stabilize the output voltage, that is, an automatic voltage regulation communication voltage regulator driven by a servo motor. This kind of voltage regulator has high power, good output voltage waveform, and no special requirements for load characteristics. However, the stability is low and the recovery time is long.
(4) Inductive communication voltage regulator: a device that stabilizes the output communication voltage by changing the phase difference between the secondary voltage and the primary voltage of the transformer. It is structurally similar to a wound asynchronous motor and in principle to an induction regulator. It has a wide range of voltage regulation, good output voltage waveform, and power up to hundreds of kilowatts. But because the rotor is often in a locked condition, the power consumption is high and the power is low. Other copper and iron are used more, so the production required is small.
(5) Thyristor communication voltage regulator: The communication voltage regulator using thyristor as the power conditioning element. It has the advantages of high stability, fast response, and no noise. However, due to the destruction of the mains waveform, it disturbs communication equipment and electronic equipment. (6) Relay-type communication voltage regulator: a communication voltage regulator that uses a relay as an autotransformer winding. It has the advantages of wide voltage stabilization scale, fast response speed and low production cost. It can be used for street lighting and remote homes.
With the development of power supply technology, the following three new communication regulated power supplies appeared in the 80s of the 20th century. (1) Compensating communication regulator: also known as partial conditioning regulator. The additional voltage of the compensating transformer is connected in series between the power supply and the load. With the input voltage, the intent of voltage regulation is achieved by using an intermittent communication switch (contactor or thyristor) or a continuous servo motor to change the size or polarity of the additional voltage, subtracting (or adding) the excess (or shortage) of the input voltage. The capacity of the compensation transformer is only about 1/7 of the output power, which has the advantages of simple structure and low cost, but the stability is not high. (2) CNC communication voltage regulator and step voltage regulator: The control circuit is composed of logic components or microprocessors, and the number of primary turns of the transformer is changed according to the input voltage to make the output voltage stable. (3) Purified communication voltage regulator: Because it has a good isolation function, it can eliminate the spike disturbance from the power grid and is applied.

The cause of the abnormality of the motor controlled by the inverter
The first method is that you can analyze what the cause is according to the condition displayed on the inverter, such as whether the faulty code appears normal, whether there is still running code or not, and still nothing appears (in the case of input power), which means that there is a rectification problem. If you're on standby...
