 To design the hybrid of micro thermoelectric and stirling
engine for power generation.
 To optimize the output power of the hybrid system.
 Efficiency 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.
 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
