Dv/Dt filter are used for output side of the converter. It can smooth filtering by reducing the transient voltage dv/dt, and prolong the motors service life.
reduce eddy-current loss and the leak current caused by the harmonics, so as to protect the IGBT power switching components inside the frequency converter.
Only Focused on transformers, but we offer customized different types of transformers.
