Regenerative braking is active inverter technology, regeneration of power inverse to AC grid frequency and phase echo power, to achieve the braking. To achieve the regenerative braking, it is necessary to contribute to the power the same frequency with phase control, contribute to the current control conditions, served to contribute to energy security on the work. And avoid braking on the environment and equipment damage. In sectors such as electric lootives has achieved satisfactory results. In the emerging new power electronic devices, costeffective case has broad application prospects of continuous improvement. Keywords: directcurrent motor Regenerative braking 4 第 1 章 緒論 、電動(dòng)機(jī)的工作狀態(tài) 電機(jī)是利用電磁作用原理進(jìn)行能量轉(zhuǎn)換的機(jī)械裝置。直流電機(jī)能將直流電能轉(zhuǎn)換為機(jī)械能，或?qū)C(jī)械能轉(zhuǎn)換為直流電能。將直流電能轉(zhuǎn)換為機(jī)械能的叫做直流電動(dòng)機(jī)，將機(jī)械能轉(zhuǎn)換為直流電能的叫做直流發(fā)電機(jī)。 直流電動(dòng)機(jī)的主要優(yōu)點(diǎn)是起動(dòng)性能和調(diào)速性能好，過載能力大。因此，應(yīng)用于對(duì)起動(dòng)和調(diào)速性能要求較高的生產(chǎn)機(jī)械，
