Abstract

"Global warming" which is caused by the increase in greenhouse gases as a result of human activities' such as fossil fuel burning and deforestation to increase production etc., leads to higher average temperatures of the earth's near-surface air and a variety of abnormal phenomena. We must therefore realize new technological innovations that are environmentally friendly as soon as possible. A final goal toward achieving a zero pollution society is to utilize electricity produced by renewable energies' such as biomass fuels. The Stirling engine can produce mechanical power and electricity from any heating source and thus allows to reduce "Global warming" by using renewable energies. However there are few applications that allow electricity to be obtained via the Stirling engine directly from biomass fuels. In this paper we describe in detail a fundamental electrical characteristic of the Stirling engine generator with a series resonance circuit, connected to a power line. The results of experiments and the proposed approximation model show optimal operation giving maximum output power and a higher power factor. The results provide important information and guidelines for practical applications of the Stirling engine generator.
