Shaojie Chen,Wei Tao,Hui Zhao,Na Lv is analyzed. It is found that the CM and DM noises affect each other, leading to mixed-mode noise. To suppress the mixed-mode noise, the DM capacitors can be added at the AC and DC sides of the rectifier bridge. After that, the CM and DM noise equivalent circuits are derived, which provide the basi

For the convenience of analyzing the CM noise, the transformer inter-winding capacitances are usually converted into lumped capacitances. In this chapter, a generalized lumped cap

As a result, the displacement current flowing through the parasitic capacitance between the phase-leg midpoints and the protective earth (PE), as well as the tr

Zhifen Zhang,Guangrui Wen,Shanben Chennch is introduced to reduce the CM noise in DC-DC converters. As the duality, this chapter proposes the CM voltage cancellation (CMVC) method for reducing the CM noise, and its applications in the basic non-isolated and isolated DC-DC converters and practical considerations are presented. Finally, t

However, the CM current at the output side should also be addressed, as it can affect the normal operation of sensitive loads, such as the devices with touch screen. Therefore, it is necessary to reduce the CM currents at both the input and output sides. In this chapter, the CM noise mode

Then, building upon the CM voltage cancellation (CMVC) method for DC-DC converters presented in Chap.?., the CMVC method for DC-AC inverters is
