Operator-based MPPT control system for thermoelectric generation by measuring the open-circuit voltage

摘要

In this paper, a maximum power point tracking (MPPT) control system for thermoelectric generation is proposed. The MPPT algorithm is based on the open-circuit voltage method. Model equations of the thermoelectric generation circuit including a thermoelectric generation module (TEM), a DC-DC converter and an electric load are explained. The MPPT control system based on operator theory is designed for the model equations. In order to verify the proposed system, demonstration results by simulation and experiment are shown.
