Hi

I am trying to calculate the DC bus voltage ripple, I have attached the schematic diagram that I drawn up on a simulator. It also shows my method of calculating the ripple voltage on DC bus, but for some reason this ripple voltage is not the same as what I am getting from the simulator "not even close" what is my mistake??

Thanks
