調(diào)功平衡器軟件設(shè)計(jì)的探究。據(jù)調(diào)功平衡的功能要求,MCU的主程序流程圖在上電復(fù)位以后,MCU首先初始化,主要完成I/O口線的方向A/D、PWM轉(zhuǎn)換條件的設(shè)置等工作,隨后判斷K1是否閉合。未閉合表示調(diào)功平衡器未接入,即進(jìn)入監(jiān)測(cè)程序支路,清口線RB3、RB4,釋放RL1、RL2,使兩臺(tái)中頻電源的調(diào)功信號(hào)直通。在調(diào)功平衡器未介入時(shí)仍需調(diào)用A/D轉(zhuǎn)換子程序,將隔離變送器采集的中頻電源內(nèi)部調(diào)功信息轉(zhuǎn)換成數(shù)字量數(shù)據(jù),再調(diào)用串行通信子程序輸出,用于上位微機(jī)顯示、記錄等。
變頻器的冷卻條件大為改善。變頻器所有器件可分布安裝在雷內(nèi)殼體圓周,省卻了體積較大的散熱器。入水運(yùn)行時(shí),就會(huì)對(duì)這些器件進(jìn)行水冷,器件的功率負(fù)荷能力得到較大的提高。因此,輸出功率相同時(shí),用變頻器的體積和重量可以做得比普通變頻器小很多。
變頻調(diào)速作為一項(xiàng)成熟技術(shù)已廣泛應(yīng)用于各個(gè)工業(yè)領(lǐng)域,國(guó)內(nèi)不少單位從事變頻器及相關(guān)功率器件的研究和生產(chǎn),從技術(shù)上講,研究適合使用的變頻調(diào)速器是完全可行的。變頻器可從下述幾個(gè)方面進(jìn)行研究:專(zhuān)用器件的研究,解決雷內(nèi)安裝所需特定形狀的功率器件安裝方式問(wèn)題;工作機(jī)理研究,解決與電動(dòng)機(jī)的參數(shù)匹配間題,保證電機(jī)系統(tǒng)具有所需的轉(zhuǎn)速變化范圍和輸出功率。
協(xié)同動(dòng)作機(jī)制研究,解決與相關(guān)系統(tǒng)協(xié)同動(dòng)作問(wèn)題,保證電動(dòng)機(jī)系統(tǒng)按預(yù)定程序和轉(zhuǎn)速運(yùn)轉(zhuǎn)??傊?,變頻調(diào)速異步電動(dòng)機(jī)動(dòng)力系統(tǒng)在設(shè)計(jì)、制造方面具有可行性,同時(shí)由于其造價(jià)低、維護(hù)使用方便,具有優(yōu)越的技術(shù)性能,一旦技術(shù)成熟并投入使用,將產(chǎn)生較高的軍事效益和經(jīng)濟(jì)效益。
