摘要
A device, system and method for harvesting electrical power from hydraulic fluid of a hydraulic system determines at least one of hydraulic fluid flow or hydraulic fluid pressure in the hydraulic system. Based on rules and the determined at least one of the hydraulic fluid flow or hydraulic fluid pressure, an expected conversion efficiency of the power conversion device and an expected rectified power to be generated from the received input power by the power conversion device are determined. From the expected rectified power a potential conversion efficiency of the power conversion device is determined, and the power conversion device is commanded to produce the expected rectified power when the potential conversion efficiency is greater than or equal to the expected conversion efficiency. When the potential conversion efficiency is less than the expected conversion efficiency, the rules are updated.
