摘      要

逆變電源從出現(xiàn)到發(fā)展已經(jīng)有很多年了，它的應(yīng)用也己經(jīng)不只是普通的應(yīng)急設(shè)備了，它在節(jié)能、變頻調(diào)速以及改善電源質(zhì)量等很多方面被廣泛利用。隨著電力電子器件的不斷更新?lián)Q代，更高耐壓更大功率更低損耗是逆變電源的發(fā)展趨勢(shì)。
本文詳細(xì)地分析了在逆變電源主電路中，各個(gè)元器件的作用以及其具體的選擇方法。
文章從功率模塊的物理結(jié)構(gòu)入手，重點(diǎn)介紹了英飛凌公司第三代模塊的先進(jìn)之處和工作特性。文章是在查閱了大量的理論資料，參考了國(guó)內(nèi)外各種各樣的電路后，整理并完善出的整個(gè)主電路的設(shè)計(jì)方法。
關(guān)鍵詞：逆變電源，IGBT模塊，均壓電阻，開(kāi)關(guān)損耗

Abstract

There are many years from the power inverter have already appeared to the development. Its applications now are much more than only met the emergency equipment. It is used in many areas such as energy saving,  VVVF, the improvement of power supply quality and so on. With the development of power electronic devices, the trend of the power inverter is higher voltage, big power and lower loss.   
This article analyzed each component in detail of the main circuit of power supply.
The article introduced the physical structure and electric properties of the power module. the design was born. Several waveforms such as soft start, gate drive signal and so on. In the document, there raised a method for choosing the equal resistance.

Key  words：power  inverter，IGBT  module, ，equal  resistance，switch loss
