基于matlabsimulink的單相橋式全控整流電路仿真電力電子論文-預覽頁
【正文】 橋式全波可控整流Abstract:Many types of rectifier,according to the rectification of the voltage wavefrom to the sub,a halfwave rectifier,fullwave rectifier。 controlled by the principle rectifier and phased into high Rectifier frequency,and so on.MATLAB simulation tool developed by one of its main functions is achieve dynamic systems modeling, simulation and analysis.Keyword:SIMULINK。當電源電壓過零時，電流也降到零，Vt1和Vt4即關斷。一個周期內(nèi)整流電壓脈動兩次，脈動程度比半波時要小。整流輸出電壓的平均值為Ud = 1παπ2Usinωtd(ωt) = (22Uπ)1+cosα2 = +cosα2它是半波電路的兩倍。由仿真波形我們可以直觀地看出晶閘管導通角的變化對負載電壓的影響。
