Noise-Source Model for Frequency-Domain EMI Simulation of a Single-Phased Power Circuit

Application of Frequency-Domain Noise-Source Model to Simulation of Time-Synchronized Near-Magnetic-Field Distribution above a Power Circuit

“…The evaluated power circuit is the same as that in [25]. The nearmagnetic-field distribution above the power circuit is newly evaluated in this paper.…”

“…Rdion is the measured forward DC resistance when 6 A current is flowing in the diode. We proposed the noise source model in [25]. We used the frequency domain solver of CST Microwave Studio for a three-dimensional electromagnetic simulation [28].…”

“…We used the frequency domain solver of CST Microwave Studio for a three-dimensional electromagnetic simulation [28]. The three-dimensional model of the evaluated power circuit for the finite-element analysis is the same as that in [25]. The three-dimensional shapes of busbars, the ground plane, PCBs, CX, CY, Cout, and Lout are modeled for the finiteelement analysis.…”

“…Although simulation models for the nearmagnetic-field distribution are proposed in [13], [14], and [16], the time-synchronized near-magnetic-field distribution is not considered. We proposed the frequency-domain noise-sourcemodel for a time-synchronized EMI noise simulation in our previous work [25]. The validity of the proposed model was shown via evaluation of the EMI noise level observed at LISNs.…”

“…In this paper, we study the validity of the frequency-domain noise-source-model proposed in [25] via evaluation of the timesynchronized near-magnetic-field distribution above a power circuit. We evaluate the near-magnetic-field distribution maps for turn-on and turn-off of the transistor, respectively.…”
