我用F28M35做三相PFC整流电路，在矢量控制模块SVGEN.H与波形输出模块F28M35xPWM.H配合输出的结果总是不正常，表现在PFC部分，最小升压为1.8倍，逆变状态输出波形峰值比应该输出峰值低1.8倍。
如果您使用过SVGEN.H这个程序做过电机控制或者整流控制，请指出我引用的两段程序在哪里出了问题？
参考SVGENDQ.H的使用说明，有一个系数是Udc/√3 ，但是不知道怎么使用√3这个系数，求解答！

逆变输出波形如下：
iparkI.Ds = _IQ(1);
iparkI.Qs = _IQ(0);
直流端输入50.1VDC，交流侧空载引出
从结果可以看出，50.1VDC输入，17.9V线电压输出，相电压峰值为14.61VDC，远低于应该输出的比例28.76VDC.（28.76VDC的计算依据 50.1x310/540=28.76VDC）
逆变输出波形为
