| description | Present-day solar panels incorporate inverters as their core components. Switching devices driven by specialized power
controllers are operated in a transformerless inverter topology. However, some challenges associated with this configuration
include the absence of isolation, causing leakage currents to flow through various components toward ground. This inevitably
causes power losses, often being also the primary reason for the power inverters’ analog equipment failure. In this paper,
various aspects of the leakage currents are studied using different circuit analysis methods. The primary objective is to convert
the leakage current energy into a usable DC voltage source. The research is focused on harvesting the leakage currents
for producing circa 1.1 V, derived from recently developed rectifier circuits, and driving a 200 Ω load with a power in the
milliwatt range. Even though the output voltage level is low, the harvested power could be used for charging small batteries or
capacitors, even driving light loads. |
