1.發展現狀
變頻器是利用電力半導體器件的通斷作用將工頻電源變換為另一頻率的電能控制裝置。我們現在使用的變頻器主要採用交—直—交方式(VVVF變頻或矢量控制變頻),先把工頻交流電源通過整流器轉換成直流電源,然後再把直流電源轉換成頻率、電壓均可控制的交流電源以供給電動機。變頻器的電路一般由整流、中間直流環節、逆變和控制4個部分組成。整流部分為三相橋式不可控整流器,逆變部分為IGBT三相橋式逆變器,且輸出為PWM波形,中間直流環節為濾波、直流儲能和緩衝無功功率。
交流電動機變頻調速已成為當代電機調速的潮流,它以體積小、重量輕、轉矩大、精度高、功能強、可靠性高、操作簡便、便於通信等功能優於以往的任何調速方式,如變極調速、調壓調速、滑差調速、串級調速、整流子電動機調速、液力偶合調速,乃至直流調速。因而在鋼鐵、有色、石油、石化、化纖、紡織、機械、電力、電子、建材、煤炭、造紙、注塑、吊車、城市供水、中央空調及污水處理行業得到普遍應用。
運動控制係統的發展變頻器是運動控制係統中的功率變換器,運動控制係統是作為機電能量變換器的電氣傳動技術的發展。當今的運動控制係統是包含多種學科的技術領域,總的發展趨勢是:驅動的交流化,功率變換器的高頻化,控制的數字化、智能化和網絡化。因此,變頻器作為係統的重要功率變換部件,提供可控的變壓變頻的交流電源而得到迅猛發展。
