Abstract

The analysis and modeling of common mode conducted EMI in the radiofrequency range (10 kHz-30 MHz) of a DC-DC boost zero voltage switching (ZVS) PWM power converter and a conventional DC-DC boost PWM power converter are compared. Noise signal measurement is carried out by means of a line impedance stabilization network (LISN). To compute the noise spectrum of LISN output in the RF range, direct simulation of equivalent noise circuits is implemented as well as an analysis in the frequency domain
