Differential Mode Noise Prediction and Analysis in Single-Phase Boost PFC for the New Frequency Range of 9–150 kHz

Abstract

From 2013 to 2018, he was the high voltage engineer expert with MONA Consultants company, where he was responsible for the design and determining specifications of HV equipment (out-door & indoor use) in 63 to 400kV substations. He is currently working toward a Ph.D. degree in power electronic systems with the

The Impact of Grid Distortion on the Power Conversion Harmonics of AC/DC Converters in the Supraharmonic Range

“…Consequently, 𝑖 𝑔(𝑆𝐻) is affected by the DBR. To determine the effect of the DBR, the following DBR function can be applied [33]; In order to estimate the i DC(SH) which represents the reflection of the i g(SH) , let i g(SH) be described by the following equation,…”

A Unified Differential Mode Noise Estimation Method and Filter Size Comparison in Single-Phase Multileg and Multilevel Totem-Pole PFC Converters

“…Many research efforts have been put into estimating the DM noise of conventional boost PFC topologies [9], [10], [11], [12], [13], [14]. In [13] and [14], DM noise estimation is analyzed for single-leg and two-leg interleaved topologies under a limited frequency range of 9-150 kHz.…”

“…Many research efforts have been put into estimating the DM noise of conventional boost PFC topologies [9], [10], [11], [12], [13], [14]. In [13] and [14], DM noise estimation is analyzed for single-leg and two-leg interleaved topologies under a limited frequency range of 9-150 kHz. On the other hand, the works [15] and [16] cover both frequency bands, i.e., 9-150 kHz and 150-30 MHz for two-leg interleaved CCM boost PFCs.…”

“…The DM noise estimation methods presented in [10], [11], and [12] require extensive model-based simulations that are time consuming and are topology-specific. The studies presented in [13], [14], [15], and [16] adopt an analytical approach with equivalent circuit modeling, which considers the switch node voltages as DM noise sources and then time-domain signals are converted to the frequency domain using fast Fourier transform (FFT). These approaches are not generalized and involve extensive mathematical computations.…”
