<p>The Invention concerns a method for smoothing alternating electric current from a number of power generators, for example windmills with variable rotational speed, where the generators are electrically connected to an electric network, and where each power generator includes a transformer with pulse width modulation for converting direct current to pulse width modulated alternating current for feeding to the network. The time for feeding the pulses of the pulse width modulated alternating current is different for each generator in order to achieve a more even alternating current as a sum of respective outputs of alternating current from the generators.</p> |
