但是VVVF缺點是輸入功率因數(shù)比較低,諧波電流大,直流電路需要大的儲能電容。變頻器的主回路構(gòu)成:電源輸入—整流橋—啟動電阻—母線電容—制動單元(制動電阻)—逆變橋—電源輸出。主電路是給異步電動機(jī)提供調(diào)壓調(diào)頻電源的電力變換部分,它由三部分構(gòu)成:整流電路:將工頻電源轉(zhuǎn)變?yōu)橹绷?;平波回路:吸收在變流器和逆變器產(chǎn)生的電壓脈動;逆變電路:將直流轉(zhuǎn)變?yōu)轭l率可調(diào)的交流電。主要參數(shù)測量對與其工作系統(tǒng)主要是由變頻器和變頻電機(jī)兩部分組成。

參數(shù)測量算法分析示波器中測量的項目大體上可分為兩大類,一類與電壓相關(guān),如值、值、頂部值、底部值等。另一類與時間相關(guān),如頻率、周期、上升時間、下降時間、占空比等。頂部值、底部值是非常重要的兩個測量項,是時間測量的基礎(chǔ)。與電壓相關(guān)的測量,相對比較簡單,值(Vmax)與值(Vmin)可通過遍歷所有樣本點求出。頂部值(Vtop)和底部值(Vbase)的求解,需要先對所有樣本點進(jìn)行直方圖映射,然后求出現(xiàn)概率的電壓值。
