To design the hybrid of micro thermoelectric and stirling engine for power generation.
To optimize the output power of the hybrid system.
Problem statementEfficiency of the Stirling engine drops if the
temperature difference between the hot and cold ends decreases.
Efficiency of the thermoelectric drops if the temperature difference between the hot and cold ends decreases.Scope of research
Integrate the design of thermoelectric and stirling engine
Optimize the output power by using DC-DC Buck Boost Converter
Analysis hybrid system performance such as voltage, current, power, speed and temperature
This project discusses the design and development of a hybrid micro thermo-electric and Stirling engine for power generation electric based on new alternative energy method. This design of power generation is combination between two types of source that are the thermo-electric and Stirling engine. The purpose of this project is to development the one of system for power generation of a micro thermo-electric and Stirling engine that capable of operating on a variety of heat sources, specifically on waste heat. This project aims to combine the two of sources such as micro thermo-electric and Stirling engine is to generate the optimum electric energy in a short time. The PSpice is used to simulate the data analysis before design the real prototype. It will help to understand the flow of design and easier to manage the components are needed in this design.
The purposed system is use TE device that directly convert heat energy to electricity to charge a battery.
A SEPIC DC-DC Controller used to maximum the output voltage
Design and a prototype implementation of a maximum power point tracker (MPPT) for a thermoelectric (TE) module aiming to improve energy conversion efficiency in battery
charging. This system uses TE devices that directly convert heat energy from a water gas heater to electricity
to charge a battery.
The steam-Rankine cycle is the principle exploited for producing electric power from high temperature fluid streams. Gas and steam cogeneration and combined heat and power technologies (CHP) help to improve the electrical and total efficiencies of modern power
plants from 35% to about 60%.
The alpha configuration locates the piston and the displacer in separate cylinders, and attaches the heater and the cold sink to either cylinder. Alpha engines have
good reliability and efficiency. It used MATLAB to simulate data collection
methodology
