I have already successfully simulated a three-phase rectifier on simulink. However, I wish to implement the same on LTspice because I would have liked to see the effect of using non-ideal components. In order to make it easier and avoid whole control and feedback implementation, I imported the switching pulses datapoints from my simulink simulation into Ltspice and given them to ideal switches as shown below(for now I am starting with ideal components).
However, I am not getting the expected results. I expect a steady DC output voltage of 600V as I had obtained in my simulink simulation yet I am getting something like this:
Please point out what might be the possible reasons for this and how to solve this issue!!
