Full-Bridge Diode-Clamped Four-Level Symmetric Switching Converter

open access: yesIEEE 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 ...
