1、 Transformer: 1. What is a transformer? Transformer is a device that changes AC voltage by using the principle of electromagnetic induction. The main components are primary coil, secondary coil and core (magnetic core). In electrical equipment and wireless circuit, transformer is often used as voltage rise and fall, matching impedance, safety isolation, etc.
2. Transformer classification: transformer can be divided into two categories according to the structure: isolation transformer and autotransformer. a. What is isolation transformer? Isolation transformer principle refers to the transformer whose input winding and output winding are electrically isolated from each other
b. What is autotransformer: autotransformer refers to the transformer whose primary and secondary windings are in the same regulating winding.
3. When purchasing a transformer, we should know where the parameters of the transformer are: when purchasing the transformer, we need to judge the required transformer according to its use. Transformer capacity, input voltage value, output voltage value, efficiency, size and appearance

2、 What is a voltage regulator? The regulator consists of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator. By automatically adjusting the coil turns ratio, the output voltage is kept stable. The voltage regulator with large capacity also adopts the principle of voltage compensation. When the city voltage fluctuates, it can stabilize the voltage to a certain value, and then output the stable voltage for equipment use. No matter the fluctuation of input voltage, the output voltage of the regulator is kept in a stable range. The voltage regulator is mainly used in places where the voltage quality of the power grid is not good and the load has high requirements on voltage waveform. At the same time, it is also conducive to filtering the abnormal situations such as overvoltage from the city telex and protecting the equipment,

2. Definition of voltage regulator: voltage regulator is a kind of equipment that provides stable output voltage according to the demand of electrical equipment. It can automatically adjust the output voltage. Its function is to stabilize the power supply voltage which has large fluctuation and does not meet the electrical requirements of electrical equipment within its set value range, and the electrical equipment can work normally under the rated working voltage by using various circuit workers. 3. Application of voltage regulator: the voltage regulator is suitable for the places sensitive to the fluctuation of working voltage. And all need to stabilize the power supply voltage.
