摘要：
隨著電力電子技術(shù)、微電子技術(shù)、自動(dòng)控制理論的發(fā)展，交流調(diào)速系統(tǒng)的應(yīng)用得到了廣泛的發(fā)展，并逐步取代了直流調(diào)速系統(tǒng)，成為20世紀(jì)后期以來(lái)人類社會(huì)的重大技術(shù)之一，科學(xué)技術(shù)發(fā)展的熱點(diǎn)話題。
變頻調(diào)速又是一種應(yīng)用很廣的交流調(diào)速系統(tǒng)。該論文對(duì)各種調(diào)速系統(tǒng)的特點(diǎn)進(jìn)行了分析，最終選定了一種在電氣傳動(dòng)領(lǐng)域中的論證方案，即交-直-交電流源型變頻調(diào)速系統(tǒng)。然后分別針對(duì)主回路、控制回路的各個(gè)環(huán)節(jié)進(jìn)行分析，還進(jìn)行了有關(guān)參數(shù)的計(jì)算和選擇。
該論文為了保證實(shí)驗(yàn)裝置的調(diào)速性能，還增加了一些輔助環(huán)節(jié)，如過(guò)電流、過(guò)電壓的保護(hù)等。最終實(shí)現(xiàn)了所要研究的目的

Summary：
With the development of electric and electronic technology , microelectric technique , automatic control theory, the application in transfer speed systematic get extensive development , and replace direct current transfer speed systematic progressively to exchange. it has become great one of technology of human society since the later stage the 20th century.
It is that very wide exchange of a kind of application adjusts the speed systematically that frequency conversion adjusts the speed. This transfer thesis analyse and select to various kinds of speed systematic characteristic . Then it analyses to the main return circuit , each the return circuit of controlling separately, and carries on the calculation and choice about the parameter.
This thesis has also increased some auxiliary links ,in order to guarantee adjusting speed performance of the experimental provision, such as passing protection of the electric current , overvoltage ,etc.. It have realized the purposes studied finally。
