摘要: Traditionally, switched-capacitor (SC) converters have suffered from high transient currents, which limit both the efficiency and power density of such converters. Soft-charging operation can be employed to eliminate current transients greatly improve SC In this approach, a second-stage magnetic converter is cascaded with stage act as controlled load. Another approach use resonant zero-current switching. This paper shows that soft-charging operations are closely related, technique will proposed, achieves either by adding single inductor existing topologies. addition, since most preexisting or were devised in an ad-hoc manner, formulates analytical method determine whether conventional topology compatible proposed approach. A number common topologies analyzed, including Dickson, series-parallel, ladder, Fibonacci, doubler configurations. Through comparison simulated results, well experimental work, validated family high-performance obtained.
