ABSTRACT:
An improved method and apparatus for operating an inverter comprising two sub-inverters having their outputs connected with each other through a choke with a center tap in which the outputs are controlled such that two AC output voltages displaced in phase with respect to each other are applied to the choke. According to the present invention in order to minimize the voltage-time area at the choke, the two AC voltages are reversed in polarity within the range of the control angle at least once with reversals in the two voltages always taking place at the same time and in opposite directions.
