Hi, i'm having a problem while running a simulation of a Bridge Rectifier on PSpice. This is my circuit schematic: http://img521.imageshack.us/img521/276/q1tasks2schematicsxp3.jpg Vs is at 15sin(100*pi*t). And this is the input and output waveforms plotted by PSpice. http://img338.imageshack.us/img338/6281/untitledpb6.jpg I'm aware that my input wave should have a symmetrical peak-to-peak value but i can't get it on PSpice. I have asked around and was assured that my schematic and output wave is ok, but there's no answer to why my input wave is like that . Using PSpice Student Version 9.1. Thanks in advance!
