## dc central point SOLVED

 Hi, I am studying three-phase inverters, and I came across the concept of "dc central point." Now, I (think) I understand the theory, but what does it practically mean? I have an inverter in my basement, how should I be able to measure with respect to this dc central point? Could someone explain the real meaning of this theoric concept?

 If three wires carry Vsin(wt), Vsin(wt + 2pi/3) and Vsin(wt + 4pi/3) then these average zero, which is the central point. This is useful in power distribution systems where power is generally transmitted along the three wires, but is finally transmitted to domestic properties along one phase each with the centre as return. If the load on all three phase wires is approximately equal then the current in the centre wire is near zero and it can be of smaller diameter.

 Hi, thank you for your answer. It is confusing for me because the "dc central point" is explained on the dc side. But I think I got the concept 0 votes by kleyton June 11, 2018
