This study presents a common-mode inductor design for parallel interleaved converters, which integrates the inter-phase and boost inductors together in a novel structure. It is shown that the proposed magnetic structure accommodates a wider range of desirable electromagnetic parameters.
The common mode inductor is an integral part of most EMI filters; its very high impedance over a wide frequency range suppresses high frequency power supply spikes. power supplies gener-ate two types of noise: common mode and differential mode. Differential mode noise (Figure 1a) follows the same path as the input power.
The basic parameters needed for common mode inductor design are input current, impedance, and fre-quency. Input current determines the size of the conductor needed for the windings.
Popular opinion states that com-mon mode inductors cannot be satu-rated; the differential mode flux within the core cancels and the com-mon mode flux is so low that it is not a concern. Unfortunately, this is not entirely true. It has been shown by others [4,5] that some amount of dif-ferential flux exits the core from each winding.
In this context, three-phase common-mode (CM) inductors find a large application in areas such as adjustable-speed drives , , UPSs , renewable energy, process technology, battery charging for electric vehicles, power supplies for IT , future more electric aircrafts, and others.
