Abstract :
The mechanism of noise suppression by a magnetic snubber is analyzed quantitatively. The snubber consists of a parallel circuit with a saturable reactor and a linear inductor connected in series with a small diode. The effects of the magnetic characteristics of the saturable reactor and the linear inductor on the surge and noise are examined by comparing analytical and experimental results.<>
