TL;DR: The 3LT2C as mentioned in this paper combines the positive aspects of the two-level converter such as low conduction losses, small part count and a simple operation principle with the advantages of the three-level converters such as the low switching losses and superior output voltage quality.

TL;DR: In this article, an isolated three-port bidirectional dc-dc converter composed of three full-bridge cells and a high-frequency transformer is proposed, where phase shift control managing the power flow between the ports, utilization of the duty cycle control for optimizing the system behavior is discussed and the control laws ensuring the minimum overall system losses are studied.

TL;DR: The impact on the system-level performance, i.e., efficiency, power density, etc., of industrial inverter drives and of dc-dc converter resulting from the new SiC devices is evaluated based on analytical optimization procedures and prototype systems.

TL;DR: In this article, three-phase power factor correction (PFC) rectifier topologies with sinusoidal input currents and controlled output voltage are derived from known single-phase PFC rectifier systems and/or passive 3-phase diode rectifiers, and their functionality and basic control concepts are briefly described.

TL;DR: An efficiency-optimized modulation scheme and design method are developed for an existing hardware prototype of a bidirectional dual active bridge (DAB) dc/dc converter, and the average efficiency rises from 89.6% to 93.5%.
