Principle and Application of Hall-effect current sensor
Aug 06 , 2020
The power factor correction (PFC) circuit and inverter circuit in the telecom rectifier and server power supply unit (PSU) all need to detect the current signal on the high-voltage side to the controller on the low-voltage side, so an isolated current sensor is used. There are many ways to implement isolated current detection, such as current transformers (CT), isolation amplifiers, and Hall effec...

What is the difference in working principle between current transformer and voltage transformer
Sep 17 , 2020
Working principle of current transformer The working principle of the current transformer is similar to that of the transformer. The most critical difference with the voltage transformer is that under normal operation, the pressure drop on the primary and secondary windings is not large, which is equivalent to a transformer with a short-circuit fault condition. Therefore, the magnetic flux Ф in th...

Let's talk about inductors today to see how it works
Sep 17 , 2020
Principle and main function of inductors Inductor is an electronic component that can convert electrical energy into magnetic energy, store it under appropriate conditions, and then release it and then convert it into electrical energy. The most important role of inductor is electromagnetic conversion. Inductor All electrical conductors (transmission lines) will cause electromagnetic fields when p...

What role can the reactor play
Sep 18 , 2020
Reactors are also called inductors. When an electrical conductor is connected to the power supply, it will cause an electromagnetic field in a certain space occupied by it. Therefore, all electrical conductors that can carry current are inductive in a general sense. The inductive load must absorb the active current and reactive current of the power grid to operate, so that the power grid can impro...

The main function of reactor
Sep 18 , 2020
Reactors are also called inductors. When an electrical conductor is connected to the power supply, it will create a magnetic field in a certain space it occupies. Therefore, all electrical conductors that can carry current are inductive in a general sense. However, if the power supply is long, the inductance of the electrical conductor is not large, and the resulting magnetic field is not strong. ...

The future development direction of electronic transformers
Oct 28 , 2020
According to media reports, the future research and development directions of electronic transformers include passive sensing, structural combination, functional reuse, and component standardization. Passive sensing: Due to the technical advantages of passive sensing, independent ECT sensing components will tend to be passive. This includes that active sensors will be self-powered and move towards...
