Vibration and noise characteristics of the inductive filtering converter transformer

摘要

Harmonic magnetic fluxes in transformer's core and harmonic currents in grid-side winding can be restrained via the inductive filtering technology. Vibration and abating noise of the core caused by the harmonic magnetic fluxes are controlled at the source, and has a good effect in reducing vibration and abating noise of the grid-side winding. Vibration and noise characteristics of the inductive filtering converter transformer are tested under load. The experimental results verify this theory.
