I. Introduction
Demands imposed on modern electric energy generation and distribution networks have sped up the development of power electronic systems [1]. Due to the widespread adoption of domestic solar photovoltaic (PV) and wind power systems, the technology of residential battery energy storage systems has attained the most interest among the rest [2], [3]. Power converters interface these energy generation and storage units, making them especially important in dc microgrids [4]. These converters can be broadly categorized into voltage-fed, impedance-source, and current-fed (CF) converters [5], [6], [7]. Recently, current-fed converters have been introduced because of their inherent benefits, such as soft switching [8], [9], resonant switching [10], use of parasitic resonance [11], and active snubber [12].
