The difference between variable frequency transformers and ordinary transformers
Author：
1、 Different working principles
The working principle of a regular transformer is to use electromagnetic induction to generate voltage changes between the two coils of the transformer through the action of a magnetic field. The proportion of voltage change is determined by the turns ratio of the transformer coil. The variable frequency transformer adds a frequency conversion circuit to the transformer circuit, which uses a frequency converter to control the frequency of AC power, achieve voltage and frequency regulation, and can output various required voltages and frequencies.
2、 Different application scope
The main purpose of a regular transformer is to reduce voltage from high voltage to low voltage or increase voltage from low voltage to high voltage, used in household appliances, power equipment, industrial machinery, and communication equipment. Variable frequency transformers are used in fields that require frequency regulation, speed regulation, and motion control, such as motors, water pumps, fans, and other variable frequency speed control equipment.
3、 Different circuit structures
The circuit of a regular transformer only has two coils, an input coil and an output coil, and the coils convert electrical energy through a magnetic field. The circuit of the variable frequency transformer includes multiple parts such as input power supply, filtering circuit, variable frequency circuit, and output transformer, and its complexity is higher compared to ordinary transformers.
In summary, although both variable frequency transformers and ordinary transformers are electrical devices used to regulate voltage, they have significant differences in their working principles, application ranges, and circuit structures. When selecting usage, it is necessary to choose according to different needs.
