Zero Phase Reactor - Delta VFD-ED Series User Manual

6-5 Zero Phase Reactor

You can also suppress interference by installing a zero phase reactor at the main input or the motor
output of the drive, depending on the location of the interference. Due to the large current passed
through the main input/motor output side, pay attention to core saturation issue. Delta provides two types
of zero phase reactors to solve interference problems.
A. Casing with mechanical fixed part
The ideal material for withstanding large current loaded for the zero phase reactor at the main
input/motor output is composite core. Core has strong saturation, and its strong resistance are many
times of simple metal magnetic materials. Thus, it can be used for high frequencies and you can get
higher impedance by increasing the number of turns.
