High Current Inverter Inductor  

High Current Inverter Inductor In the design of filter, it is assumed that the two parts of common mode and differential mode are independent of each other. However, the two parts are not truly independent, as a common mode choke can provide considerable differential mode inductance. This part of differential mode inductance can be simulated by discrete differential mode inductance. In order to make use of differential mode inductors, common mode and differential mode should not be carried out simultaneously in the design process of filters, but should be done in a certain sequence. First, common mode noise should be measured and filtered out. By means of Differential Mode Rejection Network, the differential mode components can be removed so that the common mode noise can be measured directly. If the common-mode filter is designed to simultaneously keep the differential mode noise within the allowable range, then the mixed noise of the common-mode and the differential mode should…
