   A Seamless Modulation Strategy for Step-up/down Partial Power Processing Converter (SUD-P3C)
By Chao LIU [View]
[Download]

Abstract: This paper proposes a seamless modulation strategy for a step-up/down partial power processing converter (SUD-P3C), to realize smooth mode transition and continuous output regulation. Due to the implementation of zero volt switching (ZVS) on the high voltage side, the proposed method effectively suppresses voltage spikes caused by hard switching of the high voltage side switches, resulting in improved system reliability. Moreover, according to the small-signal analysis, the two operating modes have the same output-to-control transfer function, so the converter can adopt only one unified controller rather than two dedicated ones and reduce controller design complexity. A 400 V-3 kW prototype has been built, and the experimental results verified the effectiveness of the proposed modulation strategy. Compared to the conventional modulation strategy, the power losses are reduced by up to 14 \% due to ZVS switching.

   DC Bias Currents in Full-Bridge DC-DC Converters in Context of WBG Semiconductors and High Switching Frequencies
By Niklas BADENHOP [View]
[Download]

Abstract: This paper aims to address the challenges of ever higher switching frequencies and better semiconductors with respect to DC currents in DC-DC full-bridge converters. The causes of DC offset currents as non-identical components and higher switching frequencies in combination with wide bandgap (WBG) semiconductors are explained and discussed.

   dV/dt-Based Filter Design for Motor Inverters with Continuous Output Voltage

Abstract: Wide bandgap semiconductors enable high switching frequencies and thus the integration of filters intothe inverter. The current paper addresses the design problem for the filter components such that a givendV/dt at the inverter terminals is obtained.
