Three Phase Inverter Diagram. The solaredge three phase inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best in class reliability. The circuit below shows a 3 phase inverter inverter circuit stage using h bridge mosfets configuration which receives the phase shifted pwms from the above stage and converts them into corresponding high voltage ac outputs for operating the connected 3 phase load normally this would be a 3 phase motor.

Assuming that the grid is a considered as a receptor then the voltage equation in the three phase system is given by. The main function of this kind of inverter is to change the input of dc to the output of three phase ac. A basic 3 phase inverter includes 3 single phase inverter switches where each switch can be connected to one of the 3 load terminals.
As you can see this six mechanical switch setup is more useful in understanding the 3 phase inverter working than the cumbersome thyristor circuit.
The circuit diagram of a three phase inverter is shown below. The solaredge three phase inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best in class reliability. What we will do here is open symmetrically closes these six switches to get the three phase voltage output for the resistive load. There are many basic electrical circuits for the power devices a transformer.
