博士 === 國立臺灣科技大學 === 電子工程系 === 108 === This dissertation aims to calculate the Electro-Magnetic Interference (EMI) noise of interleaved Vienna power factor correction and Phase shift full bridge (PSFB), and then design the appropriate filter. The discrete Fourier analysis method is used to differentiate the switch/diode waveform rise/fall time and then perform Fourier transform to obtain the noise in the frequency domain, the noise value of the spectrum is passed through the cicuit equivalent path of the common mode and the differential mode, finally noise across the line impedance to stabilize the network(LISN), obtain the common mode and differential mode noise of the Vienna and PSFB. Factors resulting in higher noise are found from the mathematical model. According to the converter architecture, the filter topology is analyzed and selected, and the mathematical model is used to subtract the limit value to obtain the noise attenuation value. In the end, the filter parameters are designed, and they comply with the specification of electric vehicle CISPR 22 Class A.
