EMI issues in high power and high level diode-clamped converters [PDF]
2009 Electromagnetic Compatibility Symposium Adelaide, 2009 Planar busbar is a good candidate to reduce interconnection inductance in high power inverters compared with cables. However, power switching components with fast switching combined with hard switched-converters produce high di/dt during turn off time and busbar stray inductance then becomes an important issue which creates overvoltage. It is necessary

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

Implementation of artificial neural network based controller for a five-level converter based UPQC
Alexandria Engineering Journal, 2018 To reduce the cost and complexity of the system, ANN controller is proposed for a five-level converter based UPQC which eliminates mathematical operations such as a-b-c to d-q-0 transformation and complex controllers such as DSP’s and FPGA’s,. This paper

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 ...
