Abstract :
High-frequency-link (HFL) inverters, owing to rapid advancements in semiconductor devices and magnetics, are gaining momentum in power electronics with applications encompassing solar, wind, and fuel-cell energy systems, energy storage, electric/hybrid-electric vehicles, and power quality to name a few. HFL inverters promise the potential for simultaneous improvements in power density, reliability, cost, and efficiency, which pose R&D challenges. In that regard, one cla0ss of HFL inverters, which do not employ dc-link capacitors that are often prone to long-term reliability issues, show great promise. This paper captures the essence of our work over the last several years on a new class of modulation strategy - referred to in this paper as “hybrid-modulation (HM) scheme” - for the pulsating-dc-link HFL (PDCL-HFL) inverters.
