357Electric Power Production and Transmission Simulation

The inverter has the same circuits as the rectier, with the capacitor C set between

them. The inverter’s main purpose is to transfer the maximum power to the grid. An

indicator of the relationship between the produced power and the power transferred

in the grid is a constancy of the capacitor voltage. This voltage stays equal to the

reference value by affecting the current component I
