Current sensor is a type of sensor named after measuring current. However, electric currents are diverse. The power plant can process up to 10kA of current starting from 1mA, and the current waveform also includes AC, DC, and AC+DC. Due to the different optimal measurement methods and structures for each measurement object, there are also different current sensors available. The sensors provided by Vicorv use Hall effect systems to measure current values ranging from a few amperes to several thousand amperes.

The Hall effect current sensor measures the magnetic flux proportional to the primary current, without direct contact with the primary circuit; The combination of Hall elements and magnetic circuits provides a good solution for measuring AC/DC current, with current isolation and zero insertion loss.

The schematic diagram in Figure (1) describes the basic principle of a Hall current sensor. If the magnetic flux passes through the ratio of magnetic flux to magnetic flux in the magnetic circuit, it is inserted into the magnetic circuit at the ratio of magnetic flux to magnetic flux.

Typical applications of current sensors:

Suitable for current control and overcurrent detection of various inverters

Used for general frequency converters and various power conversion devices to control and detect overcurrent. It is also used to measure the direct current of batteries.
