Efficient resonant power conversion
IEEE Transactions on Industrial Electronics, 1990 The DC analysis of a series-resonant converter operating above resonant frequency is presented. The results are used to analyze the current form factor and its effect on the efficiency. The selection of the switching frequency to maximize the efficiency is considered.

Hybrid Power Harvesting for Increased Power Conversion Efficiency
IEEE Microwave and Wireless Components Letters, 2015 This work presents a cooperative power harvesting scheme, collecting power from two or more independent ambient energy sources into a single non-linear component. It is shown that the interaction of uncorrelated signals in a nonlinear device can greatly improve the conversion efficiency of the harvester.

Half-Heusler Alloys for Efficient Thermoelectric Power Conversion [PDF]
Journal of Electronic Materials, 2016 Half-Heusler (HH) phases (space group F43m, Clb) are increasingly gaining attention as promising thermoelectric materials in view of their thermal stability, scalability, and environmental benignity as well as efficient power output. Until recently, the verifiable dimensionless figure of merit (ZT) of HH phases has remained moderate near 1, which ...
