Full-Bridge Diode-Clamped Four-Level Symmetric Switching Converter
IEEE Access, 2023 In this paper, we propose a novel full-bridge (FB) diode-clamped four-level symmetric switching converter. Multi-neighboring reference vector discontinuous PWM (MNRV DPWM) for FB topology was implemented using a symmetric half-bridge (HB)-based control ...

Compensation of Nonlinearities in Diode-Clamped Multilevel Converters [PDF]
IEEE Transactions on Industrial Electronics, 2010 The application of multilevel converters for exciting permanent-magnet machines with low-phase inductance to dc-link voltage ratios facilitates a reduction in high-frequency switching harmonics. However, converter nonlinearities and, in-particular, on-state device voltage drops, create additional low-frequency harmonics. This paper therefore proposes a
