TLDR
In this paper, a fixed-frequency zero-voltage-switching three-level DC/DC resonant converter with phase shift control between the primary and secondary sides of the transformer is presented.Abstract:
This paper presents a fixed-frequency zero-voltage-switching three-level DC/DC resonant converter By applying phase-shift control between the primary and secondary sides of the transformer, the converter can operate at a fixed switching frequency The converter can achieve ZVS operation in the entire load range by using the magnetizing inductance of the transformer In addition, the converter can operate with wide input-voltage variations without penalizing the efficiency Therefore, the converter is suitable for applications in which high efficiency and high power density are required The principle of operation for the converter is analyzed and verified on a 275 kW, 775 kHz experimental prototyperead more

A Bidirectional-Switch-Based Wide-Input Range High-Efficiency Isolated Resonant Converter for Photovoltaic Applications
TL;DR: In this article, a novel isolated topology was proposed to meet the high efficiency over a wide input voltage range requirement for maximum power point tracking in PV power conditioning systems. But the performance of this topology is limited due to the low currents, zero-voltage switching (ZVS) and low-current switching of the primary side devices, and direct power transfer to the load for the majority of switching cycle.
