Hi, Do you have any idea why my phase-phase voltage and current has DC component? It is like that my phase-phase voltage and current are shifted up; However, My line to line voltage is correct! <<

your reference point for DC side is not right. to measure the DC side voltage, you should measure the DC+ to DC-, not to the ground.

sorry, i made a mistake. maybe you can try this. put 2 voltage source in series, whose value is half of the original one. then put the voltage reference on the middle of it.
