Method and device for reducing harmonics system perturbations in a self-commutated multilevel inverter |
摘要 |
<p>A method and an apparatus for reducing harmonics mains-power-supply perturbations of a self-commutated multilevel inverter which is clocked at the fundamental frequency and has capacitive storage devices. On one hand, when a predetermined operating point of the multilevel inverter is left, angular values for turn-on and turn-off instants of individual voltage levels of the multilevel inverter are calculated for a newly determined operating point. On the other hand, a terminal voltage of the multilevel inverter is matched to an altered fundamental amplitude of the inverter output voltage. Consequently, the harmonics mains-power-supply perturbations of a multilevel inverter can be kept to a minimum at any time.</p> |
