ABSTRACT:
A self-commutated inverter has two alternately conducting main branches which, in series with each other, are connected to a d.c. voltage source. The point of connection of the main branches constitutes the phase terminal of the inverter and a turn-off circuit is connected to this connection point. Each main branch includes a commutating inductor at least one of which is provided with an auxiliary winding. The auxiliary winding is connected in series with diodes means and this series connection is connected to the d.c. voltage source for feedback of surplus energy in a commutating circuit and symmetrization of commutating capacitor voltage.
