FAQ

1.What is the role of DC reactor?

Dc reactor, also known as dc flat wave reactor, used for the dc side of the converter, reactor through the ac current with the amount of alternating current its effect is to accumulate the amount of alternating current at a certain value.

2.What is the difference between dc reactor and ac reactor?

Ac reactor for ac control circuit, there are three-phase ac reactor and single-phase ac reactor for dc system software control circuit, only single-phase electricity.

3.What is the function of ac reactor?

Reduce the harmonic surge and valley current of main switching power supply; Improve the anti-interference ability of high-frequency transmission.
