Abstract

This paper provides a methodology for deriving a family of output characteristics (DC-side I-V and P-V curves) for a passive magnetic energy harvester (MEH) clamped on a sinusoidal current-carrying conductor. It is demonstrated that MEH characteristics depend on primary current magnitude and frequency as well on load voltage. First, expressions for power harvested by a MEH are derived employing nonlinear B-H curve approximation of the core. Then, conversion losses are assessed to provide respective estimates for the power provided by the MEH to the load. Presented analytical findings are accurately supported by experimental results of MEH designed to harvest up to 240W from a conductor carrying currents of up to 350A.
