A modular multilevel DC-DC converter with self-energy equalization for DC grids
( John Wiley and Sons Inc , 2021 , Article)Medium-/High Voltage DC grids are interesting for the integration of renewable energy sources. DC-DC conversion systems are highly needed for the development of DC grids. Recently, Modular Multilevel Converter (MMC) is the ... -
Area spectral efficiency of underlay cognitive radio transmission over rayleigh fading channels
( IEEE , 2013 , Conference Paper)Cognitive radio is a promising technology to improve the spectrum utilization by allowing the unlicensed (secondary) user share a frequency bandwidth with the licensed (primary) owner under the condition that no harmful ... -
Fundamental output voltage enhancement of half-bridge voltage source inverter with low DC-link capacitance
( Korean Institute of Power Electronics , 2018 , Article)Conventionally, in order to reduce the ac components of the dc-link capacitors of the two-level Half-Bridge Voltage Source Inverter (HB-VSI), high dc-link capacitances are required. This necessitates the employment of ... -
Generalized area spectral efficiency of wireless ad-hoc networks over Rayleigh fading
( Korean Institute of Communication Sciences , 2020 , Article)Generalized area spectral efficiency (GASE) was introduced as a metric to quantify the spectral utilization efficiency of wireless transmissions. Unlike other performance metrics, GASE takes into account the spatial property ...
