In Hazardous environment industries where the emission of toxic gases and effluents will have an impact on the health of the operators, the recording of health parameters of individual operators is very important. In such situation the health monitoring of operators are being monitored and processed centrally by a server and this can be powered by a system of batteries which can be operated from TEG to ensure reliability and to utilize the exhaust heat energy of industries for better performance. This paper describes the Thermo electric generator with battery that supports medical server. The thermoelectric generator converts heat energy into electrical energy. Mathematical model of thermoelectric generator was developed in MATLAB SIMULINK. This exhibits different voltage and current for various temperature differences. The proposed system uses maximum power point tracking algorithm to obtain the maximum power from the thermoelectric generator. This algorithm is developed in embedded MATLAB controller, which gives the firing angle to the DC-DC Boost converter for various temperature differences. This will increase the efficiency of the system.
