高頻高壓電源的升壓與降壓時間是怎么看的呢？電捕焦油器高頻電源廠家介紹電除塵器高頻電源查看升壓與降壓的方法(fa)：

通常(chang)情況下，我(wo)們(men)是(shi)通過(guo)控(kong)制逆變(bian)器(qi)(qi)饋(kui)電(dian)(dian)(dian)給電(dian)(dian)(dian)壓(ya)(ya)(ya)倍(bei)增(zeng)電(dian)(dian)(dian)路相連的(de)(de)升壓(ya)(ya)(ya)變(bian)壓(ya)(ya)(ya)器(qi)(qi)而產生高(gao)電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)。倍(bei)增(zeng)電(dian)(dian)(dian)路(電(dian)(dian)(dian)容器(qi)(qi)和二極管組成)，使用了這一(yi)工作(zuo)原(yuan)理：那就是(shi)充電(dian)(dian)(dian)電(dian)(dian)(dian)容和放電(dian)(dian)(dian)電(dian)(dian)(dian)容每隔交流電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)半個周期，此時(shi)的(de)(de)輸出是(shi)這些電(dian)(dian)(dian)容器(qi)(qi)串聯電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)總和。電(dian)(dian)(dian)壓(ya)(ya)(ya)倍(bei)增(zeng)電(dian)(dian)(dian)路具有電(dian)(dian)(dian)容性質(zhi)，并(bing)有儲存和保持(chi)電(dian)(dian)(dian)荷的(de)(de)能力。

為了提升效率，電(dian)(dian)(dian)源內(nei)部輸(shu)出端連接(jie)的(de)(de)電(dian)(dian)(dian)阻(zu)路徑，是具有高阻(zu)抗的(de)(de)電(dian)(dian)(dian)壓反(fan)饋分壓器電(dian)(dian)(dian)阻(zu)串。反(fan)饋分壓器產生低電(dian)(dian)(dian)壓對地參考的(de)(de)電(dian)(dian)(dian)壓反(fan)饋信號(hao)以控制和調節電(dian)(dian)(dian)源。

由于倍增器裝置中的二極管的方向，正極性的電源只能提供電流而無法吸收電流。因此，在空載狀態下，反饋分壓器子串就成為了輸出的放電路徑。讓我們來看一款典型產品的倍增器電容值和反饋分壓器電阻值，以了解我們所談論的是何種空載放電RC時間常數。

在空載情況下，輸出放電需要如何足夠長的時間。如果外部負載連接到電源的輸出端，放電時間常數就可以大大的縮短。出于這個原因，高壓電源的下降時間是負載決定的。當您使用高壓電源時，請記住這一點。
