How A Three Phase Inverter Works? As most people know, inverter can be divided into two types: single-phase inverter and three-phase inverter.

And the main function of inverters that is to convert DC into AC current. Also due to the discrepancy of voltage rate, single phase is more for household use, and three phase inverter is commonly used in higher power applications.

So How a three phase inverter works and what is the three phase inverter?

Three phase inverter means that the converted AC voltage is three phase, namely AC 380V. The three phase power is composed of three AC potentials with the same frequency, equal amplitude, and 120°out of phase each other, which can carry three-phase loads.


Meanwhile, The three phase inverter supports 100% three phase unbalanced load, for that reason it can also carry single-phase load. In case your house has a three phase power connection, then it can be connected to any single phase by go through only one phase.

Let us further explain, user can connect one of Live Wires, and the common Neutral Wire to form a single phase line. And its voltage equals to what we usually call 220V. This is how your home appliances can have electricity from three phase, each phase and its neutral point of the three-phase power supply can form a single-phase loop to provide electrical energy for household users.

And nevertheless, for some electrical devices with relatively large power, the normal household voltage cannot withstand, so there will be three-phase electricity connection ways:
1)Three phase five-wire system: 3P+N+PE, namely with 3 Live Wires + 1 Neutral Wire + 1 Earth Wire;
2)Three phase four-wire system: 3P+N, namely with 3 Live Wires + 1 Neutral;
3)Three phase three-wire system: 3P, namely with 3 Live Wires only;

In view of the above, Three phase inverter can definitely meet those loads with larger voltage require, as three phase inverter has more stable and wider output by equipped a triple transformer set. Nowadays, It is applied for a plenty number of inductive and impact load devices in industry field.
