 一、制(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)单(dan)元概述  制(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)单(dan)元,全称(cheng)为“变(bian)(bian)(bian)(bian)频(pin)(pin)器(qi)(qi)(qi)专用型能(neng)耗(hao)制(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)单(dan)元”,或者(zhe)是“变(bian)(bian)(bian)(bian)频(pin)(pin)器(qi)(qi)(qi)专用型能(neng)量(liang)回(hui)馈(kui)单(dan)元”,主要用于控制(zhi)(zhi)机(ji)(ji)械负载比较(jiao)重的(de)(de)(de)(de)(de)(de)、制(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)速(su)度要求非(fei)常(chang)快的(de)(de)(de)(de)(de)(de)场合,将电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)所产(chan)生(sheng)的(de)(de)(de)(de)(de)(de)再生(sheng)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)通过(guo)制(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻消(xiao)耗(hao)掉,或者(zhe)是将再生(sheng)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)反馈(kui)回(hui)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。  二(er)、制(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)单(dan)元的(de)(de)(de)(de)(de)(de)作用  当电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)机(ji)(ji)快速(su)停车时,电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)机(ji)(ji)会反馈(kui)能(neng)量(liang)给(ji)变(bian)(bian)(bian)(bian)频(pin)(pin)器(qi)(qi)(qi),造成直(zhi)(zhi)(zhi)流(liu)(liu)母(mu)线(xian)(xian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)压(ya)升(sheng)高甚至损坏(huai)IGBT,因此需要用制(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)单(dan)元消(xiao)耗(hao)这部分(fen)能(neng)量(liang)以保护(hu)变(bian)(bian)(bian)(bian)频(pin)(pin)器(qi)(qi)(qi)。
