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 ...

Direct Current Control for Grid-Connected Diode-Clamped Inverters [PDF]
IEEE Transactions on Industrial Electronics, 2017 The accurate control of the line current, robust and dynamic behavior even under distorted grids and other system faults are the most important requirements for grid-connected inverters. Applying direct current control to multilevel inverters combines the advantages of both and is an enabling step towards improved inverter performance.

Voltage Balancing Control of Diode-Clamped Multilevel Inverter [PDF]
Journal of Electrical and Electronics Engineering, 2013 In this paper is developed a control scheme for mono-phase diode clamped inverter to achieve balancing voltages on inverter capacitors. First, it develops a control scheme without taking into account the need to balance voltage on two capacitors.

Five-level Z-source diode-clamped inverter
IET Power Electronics, 2010 This study proposes a five-level Z-source diode-clamped inverter designed with two intermediate Z-source networks connected between the dc input sources and rear-end inverter circuitry. By partially shorting the Z-source networks, new operating states not previously reported for two-level Z-source inverter are introduced here for operating the proposed
