Simscape phase to phase voltage measurement is not correct?

Hi, Do you have any idea why the phase-phase voltage and current has some DC component( I mean it is a bit shifted upward!)!? The line to line voltage is alright and placed in the center (plot 2) but the phase to ground voltage and current are wrong!

This is due the way the electrical reference is connected. to the negative terminal. To get the voltage centered in 0 what is needed is to alter the circuit such that the ground is not anymore connected to the negative terminal. You can use two DC voltage sources, each with half of the total DC voltage and the electrical reference between them.
Alternativeley, you can use to capacitors on the DC side and put the electrical reference between them.
