<p>The device has a transformer (104) that is assigned to an energy source (101) in an input side and to a power grid in an output side, where transformer test points ( 205, 206)are provided with switching units (105, 106) to change transmission ratio. An adjustable load (102) is provided on a primary side to limit the voltage of the source when the load is switched from one point to other point, where rough voltage adjustment between the source and the grid is carried out using the transformer and the fine adjustment is carried out using an inverter (103) provided downstream to the transformer.</p> |
