國產變頻器逐步崛起，現(xiàn)已逐漸搶占高端市場。上海和深圳成為國產變頻器發(fā)展的前沿陣地，涌現(xiàn)出了像匯川變頻器、英威騰變頻器、安邦信變頻器、歐瑞變頻器等一批知名國產變頻器。其中安邦信變頻器成立于1998年，是我國早生產變頻器的廠家之一。十幾年來，安邦信人以渾厚的文化底蘊作基石，支撐著成長，企業(yè)較早通過TUV機構ISO9000質量體系認證，被授予“高新技術企業(yè)”，多年被評為“變頻器用戶滿意國內品牌”。變頻器組成主電路主電路是給異步電動機提供調壓調頻電源的電力變換部分，變頻器的主電路大體上可分為兩類變頻功率分析儀變頻功率分析儀(5張)：電壓型是將電壓源的直流變換為交流的變頻器，直流回路的濾波是電容。電流型是將電流源的直流變換為交流的變頻器。

開關電源比線性電源要好。不過開關電源比較復雜，內部晶體管會頻繁切換，若切換電流尚加以處理，可能會產生噪聲及電磁干擾影響其他設備，而且若開關電源沒有特別設計，其電源功率因數(shù)可能不高。主要用途編輯開關電源產品廣泛應用于工業(yè)自動化控制、軍工設備、科研設備、LED照明、工控設備、通訊設備、電力設備、儀器儀表、設備、半導體制冷制熱、空氣凈化器，電子冰箱，液晶顯示器，LED燈具，通訊設備，視聽產品，安防監(jiān)控，LED燈帶，電腦機箱，數(shù)碼產品和儀器類等領域。主要類型編輯現(xiàn)代開關電源有兩種：一種是直流開關電源；另一種是交流開關電源。開關電源內部結構開關電源內部結構這里主要介紹的只是直流開關電源，其功能是將電能質量較差的原生態(tài)電源（粗電）。

據試驗分頻諧振的電流為正常電流的240倍以上，工頻諧振電流為正常電流的40～60倍左右，高頻諧振電流更小。在這些諧振中，分頻諧振的破壞，如果PT的絕緣良好，工頻和高頻一般不會危及設備的，而6kV系統(tǒng)存在上述條件。消除辦法從技術上考慮，為了避免鐵磁諧振的發(fā)生，可以采取以下措施：選擇勵磁特性好的Tv或改用電容式TV；在同一個10kV配電系統(tǒng)中，應盡量減少TV的臺數(shù)；在三相TV一次側中性點串接單相TV或在TV二次開口三角處接入阻尼電阻；在母線上接入一定大小的電容器，使容抗與感抗的比值小于0.01，避免諧振,；系統(tǒng)中性點裝設消弧線圈；采用自動調諧原理的接地補償裝置，通過過補、全補和欠補的運行方式，來較好地解決此類問題。
