The paper discusses the impact of Power MOSFETs (PMs) Capacitance-Voltage (C-V) characteristics on switching losses in Power Converters (PCs). A fast and robustly convergent numerical technique is adopted to analyze the sensitivity of PMs power losses with respect to their C-Vshapes. Such technique helps both in identifying desirable specifications for PMs design, and in achieving appropriate selection of PMs for PCs energy&reliability aware design. The results presented in this paper, concerning loss analysis and experimental verification for a 85V to 170V@0.5A dc-dc boost converter, highlight the PMs CVcurves impact and the valuable support of the proposed technique in PMs and PCs design.

Abstract

The paper discusses the impact of Power MOSFETs (PMs) Capacitance-Voltage (C-V) characteristics on switching losses in Power Converters (PCs). A fast and robustly convergent numerical technique is adopted to analyze the sensitivity of PMs power losses with respect to their C-Vshapes. Such technique helps both in identifying desirable specifications for PMs design, and in achieving appropriate selection of PMs for PCs energy&reliability aware design. The results presented in this paper, concerning loss analysis and experimental verification for a 85V to 170V@0.5A dc-dc boost converter, highlight the PMs CVcurves impact and the valuable support of the proposed technique in PMs and PCs design.
