Design of an inductor-less step-up ac/dc converter for 0.3 V@1 MHz vibration energy harvesting

open access: yesEnergy Reports, 2020
For vibration energy harvesting, we propose an inductor-less step-up ac/dc converter in this paper. To realize the inductor-less design, the proposed ac/dc converter consists of two converter blocks: Cockcroft–Walton circuit and charge pump.

PMSG-Based Wind Energy Conversion Systems Integration Into DC Microgrids With a Novel Compact Converter

open access: yesIEEE Access, 2020
DC microgrids (DC-MGs) are recognized as an efficient alternative for common AC-MGs. DC-MGs need fewer power electronic converters since most of distributed generation (DG) units and electronic loads operate with DC voltage.

Impedance Shaping of Isolated Two-Stage AC-DC-DC Converter for Stability Improvement

open access: yesIEEE Access, 2019
The isolated two-stage ac-dc-dc converter containing an isolated dual-active-bridge (DAB) dc-dc converter and an ac-dc rectifier has been widely used for connecting the dc sources to the ac utility grid. However, the impedance interaction between the DAB
