FRACTIONAL OPEN CIRUIT VOLTAGE CONTROLLED CONVERTER BASED THERMOELECTRIC GENERATOR

Abstract: The thermoelectric generator (TEG) is thepredominant compact, solid-state heat engine. Effectiveutilization of a heat resource using a TEG requires maximizing its power output by interposing a regulated power converter between the source and load. It is criticalto track the optimum electrical operating point through the useof power electronic converters controlled by a maximum power point tracking (MPPT) algorithm. MPPT algorithm used here is the open circuit voltage method. Using an efficient buck boost converter the power output of TEG is fed to a battery.
