本發明涉及車(che)用配件(jian)技(ji)術領(ling)域,具(ju)體地說,是涉及一種用于電動(dong)車(che)的交流(liu)電機控制器(qi)的制作方(fang)法。
背景技術:
電(dian)(dian)動(dong)車(che)因(yin)其不(bu)燃燒汽(qi)油(you)產生動(dong)力,具有環保、污染小的特點(dian),在旅游景區等對環境要求較高的地方得到廣泛的應用。現有的電(dian)(dian)動(dong)車(che)設有一個交流電(dian)(dian)機控制器(qi),用于將蓄電(dian)(dian)池輸出的直流電(dian)(dian)源(yuan)轉(zhuan)(zhuan)換成三相(xiang)交流電(dian)(dian)源(yuan)并驅動(dong)電(dian)(dian)機轉(zhuan)(zhuan)動(dong)。
現有(you)的(de)交流電(dian)(dian)機(ji)(ji)控制(zhi)器(qi)(qi)包(bao)(bao)括具有(you)一個(ge)殼(ke)體(ti),殼(ke)體(ti)通常(chang)包(bao)(bao)括一塊散熱(re)底(di)板(ban)(ban)(ban)(ban)以(yi)及位(wei)于散熱(re)底(di)板(ban)(ban)(ban)(ban)上的(de)面蓋,殼(ke)體(ti)圍(wei)成一個(ge)腔體(ti),交流電(dian)(dian)機(ji)(ji)控制(zhi)器(qi)(qi)的(de)電(dian)(dian)路板(ban)(ban)(ban)(ban)安裝在(zai)該腔體(ti)內。交流電(dian)(dian)機(ji)(ji)控制(zhi)器(qi)(qi)通常(chang)包(bao)(bao)括功(gong)(gong)(gong)率(lv)(lv)板(ban)(ban)(ban)(ban)、三個(ge)功(gong)(gong)(gong)率(lv)(lv)模(mo)塊以(yi)及交流接觸器(qi)(qi),三個(ge)功(gong)(gong)(gong)率(lv)(lv)模(mo)塊通常(chang)固定在(zai)散熱(re)底(di)板(ban)(ban)(ban)(ban)上,而功(gong)(gong)(gong)率(lv)(lv)板(ban)(ban)(ban)(ban)通常(chang)安裝在(zai)功(gong)(gong)(gong)率(lv)(lv)模(mo)塊上。
交(jiao)流(liu)電機(ji)控制器(qi)接(jie)(jie)收(shou)蓄電池(chi)輸出的(de)(de)(de)直(zhi)流(liu)電,并(bing)將直(zhi)流(liu)電逆變轉換(huan)成交(jiao)流(liu)電輸出,因此每一(yi)(yi)個(ge)功(gong)率模(mo)塊(kuai)對應于三相(xiang)電機(ji)的(de)(de)(de)一(yi)(yi)相(xiang),用于向(xiang)電機(ji)輸出U、V、W三相(xiang)電源(yuan)中(zhong)的(de)(de)(de)一(yi)(yi)相(xiang)電源(yuan)。每一(yi)(yi)功(gong)率模(mo)塊(kuai)設(she)(she)有兩(liang)個(ge)接(jie)(jie)收(shou)直(zhi)流(liu)電源(yuan)的(de)(de)(de)端子(zi)(zi),分別用于接(jie)(jie)收(shou)正極電源(yuan)及負極電源(yuan),并(bing)設(she)(she)有一(yi)(yi)個(ge)電流(liu)輸出端子(zi)(zi),向(xiang)電機(ji)的(de)(de)(de)一(yi)(yi)相(xiang)輸出電流(liu)信號。并(bing)且(qie),兩(liang)個(ge)直(zhi)流(liu)電源(yuan)端子(zi)(zi)與電流(liu)輸出端子(zi)(zi)之(zhi)間需(xu)要設(she)(she)置可控開關器(qi)件,即功(gong)率管,如晶(jing)閘管或IGBT等,用于對直(zhi)流(liu)電進行(xing)控制。
由于現(xian)在的(de)(de)(de)(de)電(dian)動車(che)使(shi)用的(de)(de)(de)(de)功(gong)率較(jiao)大(da),交(jiao)流(liu)(liu)電(dian)機控制器(qi)(qi)內形(xing)成的(de)(de)(de)(de)電(dian)壓較(jiao)高(gao)、電(dian)流(liu)(liu)較(jiao)大(da),因此諸如(ru)IGBT等器(qi)(qi)件需要承(cheng)受較(jiao)高(gao)的(de)(de)(de)(de)電(dian)壓以(yi)及(ji)較(jiao)大(da)的(de)(de)(de)(de)電(dian)流(liu)(liu)。然而,如(ru)果使(shi)用大(da)功(gong)率的(de)(de)(de)(de)IGBT將導致交(jiao)流(liu)(liu)電(dian)機控制器(qi)(qi)的(de)(de)(de)(de)生產成本(ben)過(guo)高(gao),功(gong)率擴展(zhan)不靈活,不利于電(dian)動車(che)的(de)(de)(de)(de)推廣(guang),且交(jiao)流(liu)(liu)電(dian)機控制器(qi)(qi)的(de)(de)(de)(de)制作步(bu)驟及(ji)制作工業(ye)復雜,不利于交(jiao)流(liu)(liu)電(dian)機控制器(qi)(qi)的(de)(de)(de)(de)生產。
