微功耗清潔能源存貯系統

摘要：微功耗清潔能源存貯系統包括DC/DC、AC/DC、DC/AC三種功率變換器，每種變換都采用微功耗電力電子變換技術，實現了清潔能源的高品質、高效率的存貯和并網，該微功耗清潔能源存貯系統最大特點是，只要把輸入功率中極小部份進行功率變換，就可以得到全部輸出功率，即輸入功率中極大部份既不必進行實際的功率變換，也不必通過磁芯變壓器或電感傳遞，直接到達輸出端，成為輸出功率，器件都工作在工頻，不產生EMI干擾，因此功耗極小而壽命極長，輸出正弦波不失真，安全可靠，節能環保，成本、體積、重量、功耗都是傳統貯能系統的1/10。 敘詞：電能存貯系統 微功耗 存貯和并網 Abstract：Microloss Clean Energy Storage System consists of three conversion devices of DC/DC, AC/DC, and DC/AC. Each conversion applies Microloss switching technology to achieve the storage and in power grid to be of high quality and high efficiency clean energy. The best characteristic of Micro loss Clean Energy Storage System is that it takes only a very small portion of the input power thru the power conversion process and still obtains total full output power. I.E. most input power does not need thru power conversion process and does not need thru linear transformer or inductor transmit process, it just connects to output terminal and becomes output power. The system operates at the industrial frequency and generates no EMI interference, therefore power loss is very small with a longer life. Output waveform is a pure sinusoidal wave without any distortion. The system is safe and more reliable, more energy saving and with less environmental impact. The cost, dimension, weight, and power loss of this system is about one tenth of conventional standard methods.　 Keyword：Energy Storage System, Microloss, Storage and in power grid
