一種多功能逆變電源的設計與實現

摘要：隨著現代科技的發展，逆變電源廣泛應用于各行各業。本文提出了一種多功能逆變電源的設計。主電路采用二重級聯單相全橋逆變器，主逆變器一直工作，當參考信號為突變信號，從逆變器立刻配合主逆變器工作，實現輸出電壓波形精確跟蹤�？刂撇糠质羌尤胛⒎汁h節的滯環控制，根據參考信號變化的快慢，改變滯環寬度，動態響應好，精確度高，完全數字化控制。使用Matlab仿真，仿真結果證實根據主電路和控制設計的多功能逆變電源是可行的。 敘詞：多功能逆變電源 二重級聯 滯環控制 Abstract：As the development of technology ,inverted power supply is used in all kinds of industry.A design of multifunctional power supply is proposed in this paper..Main circuit adopted dual cascaded inverter.The main inverter works all the time.The slave inverter works at once to realize output voltage wave high-precise-tracking,as long as the reference singal is chopping sigal.The control part is hysteresis control with differentiation element,which changes the hysteresis band on base of the change speed of inference signal.good dynamic response,high tracking accuracy,absolutely digital controlling.The multifunctional inverted power supply on base of main circuit and control algorithm is feasible on base of main circuit and control algorithm by simulation results of Matlab.
