TL;DR: In this article, the authors present a 2-kW, 60-Hz, 450-V -to-240-V power inverter, designed and tested subject to the specifications of the Google/IEEE Little Box Challenge, which achieves a high power density of 216 W/in $3$ and a peak overall efficiency of 97.6%, while meeting the constraints including input current ripple, load transient, thermal, and FCC Class B EMC specifications.

TL;DR: In this paper, the authors show that resonant and soft-charging operations of SC converters are closely related, and a technique will be proposed, which achieves either operation by adding a single inductor to existing SC topologies.

TL;DR: In this paper, a split-phase control scheme was proposed to enable the Dickson converter to achieve complete soft-charging (or resonant) operation, which is not possible using the conventional two-phase controller.

TL;DR: In this paper, a high-efficiency, high-power-density buffer architecture is proposed for power pulsation decoupling in power conversion between dc and single-phase ac. In the proposed architecture, the main energy storage capacitor is connected in series with an active buffer converter across the dc bus.

TL;DR: In this paper, a quantitative method that can serve as a guide to compare and design multilevel topologies for large conversion ratio applications is presented, which keeps the conduction loss and switching loss constant across the different converters and employs the passive component volume as the single performance metric.
