Control method for converting power, and electronic power converter adapted to carry out said method

A control method for converting power, the method comprising:

• converting a DC voltage into a first alternating voltage waveform using a first multi-level inverter;
• converting the DC voltage into a second alternating voltage waveform using a second multi-level inverter;
• combining the first alternative voltage waveform and the second alternating voltage waveform in parallel to obtain a first resulting alternating voltage waveform;
• converting the DC voltage into a third alternating voltage waveform using a third multi-level inverter;
• converting the DC voltage into a fourth alternating voltage waveform using a fourth multi-level inverter;
• combining the third alternative voltage waveform and the fourth alternating voltage waveform in parallel to obtain a second resulting alternating voltage waveform,
• wherein the second resulting alternating voltage waveform (AC34) is displaced in phase by approximately 180° in relation to the first resulting alternating voltage waveform and the common-mode voltages are eliminated from at least one of the alternating voltage waveforms or resulting alternating voltage waveforms.
