Carrier Frequency Of Ac Reactor

AC Reactors The carrier frequency is not a fixed value, but is determined according to its application and design requirements. The carrier frequency of the reactor refers to the frequency at which the reactor handles current changes during operation. This frequency is different from the frequency of the power system (usually 50Hz or 60Hz), and it reflects more the rate of change of the electromagnetic field inside the reactor.

In the variable frequency speed regulation system, the selection of the carrier frequency of the reactor is particularly important. For example, the iron core reactor is suitable for variable frequency speed regulation systems with frequencies ranging from 50Hz to 200Hz as incoming line reactors and output reactors; while the ferrite reactor is suitable for variable frequency speed regulation systems with a rated frequency (weak magnetic frequency) of 200Hz for asynchronous motors, a maximum frequency of 300Hz, and a maximum frequency of 600Hz for reluctance motors or permanent magnet synchronous motors.

Therefore, when selecting an AC reactor, it is necessary to determine the appropriate carrier frequency based on its application environment, system frequency, and required electromagnetic performance. At the same time, the design, material selection, and manufacturing process of the reactor will also affect its carrier frequency.
