Design and Software Implementation of Multilevel Diode Clamped Converter
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The work presented in this paper concerned with the design and software synthesis of multilevel diode clamped converter. Two topologies of this type of converters have been considered and tested. The first topology was three-level diode clamped converter, while the second one was the five-level diode clamped converter. The major

Battery charger with a capacitor-diode clamped LLC resonant converter [PDF]
8th IET International Conference on Power Electronics, Machines and Drives (PEMD 2016), 2016 The paper proposes a novel battery charger through use of two serially-connected LLC resonant converters. The first stage utilises a capacitor-diode clamped LLC resonant converter which allows operation in both constant voltage (CV) and constant current (CC) modes, as found in most battery chargers, to be realised, whilst the second stage provides the ...
