Abstract
A DC-to-AC converter including six phase modules and two capacitors, a transformer with a three-phase primary winding and with two three phase secondary windings, each phase module receiving a DC voltage from a DC voltage bus and capable of transmitting an AC current, and including a transistor, able to modulate the output voltage according to five intensity levels, the first capacitance connected between the positive portion and the midpoint of the DC voltage bus, the second capacitance connected between the negative portion and the midpoint of the DC voltage bus, the first, second and third phase module are linked by their output to a different phase of the first secondary winding. The fourth, fifth and sixth phase module are each linked by their output to a different phase of the second secondary winding of the transformer, the primary winding of the transformer is linked to an electrical power supply network.
