High Efficient Maximum Power Point Tracking for Multiple Solar Strings with GaN-Based HiLEM Circuit

This paper discusses the potentials of string based Maximum Power Point Tracking (MPPT) in ground-mounted solar power plants using the HiLEM topology. First, the functionality of the HiLEM circuit is described, then the planned setup with the HiLEM topology is presented. Finally, the operating principle is illustrated by a simulated shading scenario.
