Návrh a realizace MPPT regulátoru pro dobíjení olověného akumulátoru

Abstract

This bachelor's thesis focuses on the development and construction of a functional device for tracking the maximum power point (MPPT) and monitoring the instantaneous power point during the charging of a lead-acid traction battery. The aim is to achieve efficient accumulator charging and optimal utilization of the solar panel’s output through a selected DC/DC converter and control algorithm. The theoretical part of the thesis explains the principles of MPPT, the chosen converter topology, and various algorithmic approaches. The practical part describes the design process of a step-down (buck) converter, including calculations and component selection, as well as the design and implementation of the control algorithm. The result of the work is a fully functional device capable of operating in an off-grid system. This thesis serves as a basic guide for the design and implementation of similar systems utilizing renewable energy sources.
