Is this the correct way to simulate a three-phase full bridge (6 pulses) rectifier?
I ask because I have tried this first without the two capacitors, just one, and the capacitor seems to have discharged (or charged in other direction) in some parts of the wave.
I think this is because the line-to-line without ground reference, then I added two capacitors with a ground (that is in common to neutral) like show in the image, and it seems to work fine, but it should difficult some simulations I think.
(The line-to-neutral RMS voltage is 220V and line-to-line RMS voltage is 380V).
I'm correct about the assumption?
Also, is it acceptable (yes that depends on regulations and so on, but lets take as acceptable) to just wire a plug with line to line wiring (plus ground for safety), without the neutral wire as the equipment will not be connected to neutral?
@ConnorWolf suggested doing the differential measurement across the two rails. Although I have that in mind too, I didn't have doing it (but needed sometimes) and as it says its just implementing it by math using the difference between the two measured points. It worked, I just don't know how other components that my refer ground would get to work.
V-BUS(+) in the graph is the difference between
V-BUS(+) - V-BUS(-).
Also, from the comments of the non-reader @Naib I put the power supply floating removing the ground reference from its neutral (that I think is not what @Naib is suggesting, I will edit if it is), and putting the ground in the DC-Link without any high-impedance resistor.
