按,現今科技的日新月異,提高了人類生活的品質,但也因為快速的發展,帶給人類更多負面的傷害及危害;由於科技的進步與世界人口快速成長,因此能源的消耗與環境污染問題一直是現今社會的重點議題,而石油是目前使用最為廣泛的代表性能源,但石油開採及加工卻是非常昂貴與汙染的,大量開採石油,不僅加速地球環境汙染,且更造成地球的氣候改變,使得全球溫度不斷提高,不斷地侵蝕危害著地球上所居住的所有生物。By the way, today’s rapid advances in science and technology have improved the quality of human life, but because of the rapid development, it has brought more negative harm and harm to mankind. Due to the advancement of science and technology and the rapid growth of the world’s population, energy consumption and environmental pollution problems It has always been a key issue in today’s society. Petroleum is currently the most widely used representative energy source, but oil extraction and processing are very expensive and polluting. Large-scale extraction of oil will not only accelerate the pollution of the earth’s environment, but also cause changes in the earth’s climate. , Which makes the global temperature continue to rise, and continues to erode and endanger all living creatures on the earth.

在這樣的危害地球環境下,使得人類環保意識抬頭,也不斷的開發新型態的能源,以用來替代石油燃料開採過程與製造時所產生的危害與污染;其中,電能不僅可以做任何型態的方式儲存,也是一種可以替代石油的能源,且其可以在不破壞環境的方式下的產生,同時不會像石油燃燒時會產生廢氣造成負面影響,讓電能具有更佳的環保及安全性,使得電能若能在生產後加以好好保存,其將會是一種取之不盡的能源,所以電能的使用與保存將是一大課題,同時在電力電子相關領域方面中,該如何提升電力轉換效率且又同時降低成本和損失,已成為現今科學家及各大科技產業中所重視的其中一個環節。Under such a hazard to the earth environment, human environmental awareness has risen, and new types of energy are constantly being developed to replace the hazards and pollution generated during the extraction and manufacturing of petroleum fuels; among them, electric energy can not only be used in any type. It is also a kind of energy that can replace petroleum, and it can be produced in a way that does not damage the environment. At the same time, it will not produce negative effects like waste gas when petroleum is burned, so that electric energy has better environmental protection and safety. , So that if electric energy can be well preserved after production, it will be an inexhaustible energy source. Therefore, the use and preservation of electric energy will be a major issue. At the same time, in the field of power electronics, how to improve power conversion Efficiency while reducing costs and losses at the same time has become one of the links that today's scientists and major science and technology industries attach importance to.
