Zero-Current Switching (ZCS) for a High Step Ratio Modular Multilevel dc-dc Converter with wide voltage range operation
(IEEE, 2020)
The rise of new dc technologies is pushing the development of highly efficient dc-dc converters, especially at high voltage and high step ratio. Modular multilevel converters (MMCs) are an attractive alternative because ...
A physical approach of the test voltage function for evaluation of the impulse parameters in lightning impulse voltages with superimposed oscillations and overshoots
(Institute of Electrical and Electronics Engineers, 2016-10)
The introduction of the test voltage function or k-factor in IEC 60060-1 Ed. 3 has been an important step to ensure reproducibility and traceability in high voltage tests techniques for lightning impulses with superposed ...
