20110260543Converter device and uninterruptible power supply equipped with one such device - A three-level reversible converter comprising two main switching units respectively equipped with a first and second main switch, a main switching point, and a third main switch common to the two main switching units, comprising: 10-27-2011
20110193412Converter device and uninterruptible power supply equipped with such a device - A converter to supply an AC voltage on a modulated signal output comprising two switching units each provided with a DC voltage input and a switching output to supply pulses varying between the voltage on the input in a first switched state, and a reference voltage in a second switched state, each switching unit comprising a first switch connected between the input and the switching output to establish said first switched state, said device comprising, for each switching unit, a second switch connected between said switching output and said modulated signal output to activate said switching unit, and a third switch connected between the input of said switching unit and the modulated signal output.08-11-2011
20110110136Converter device comprising at least five DC voltage levels and uninterruptible power supply provided with said device - A multi-level converter to at least convert an AC switched voltage available on a switched voltage point into at least five DC voltage levels available on positive and negative DC voltage lines, said converter comprising two separate switching units to convert respectively positive and negative half-waves of said switched voltage, connected to the DC voltage lines respectively presenting positive and negative DC voltage levels, and wherein each switching unit comprises a switching point connected to said switched voltage point by means of change-over means.05-12-2011
20110109162Converter device and uninterruptible power supply provided with such a device - A converter to supply an AC voltage and current from three DC voltages comprising two switching units provided with first switching means connected between an input and a switching output, said converter comprising, for each switching unit, second switching means connected between said switching unit and a modulated signal output, and a switching aid circuit, said converter comprising control means acting on the second switching means associated with the switching unit that is connected to the voltage input of opposite sign to the sign of said AC voltage to establish turn-off of said second switching means when said AC voltage and said AC current are of opposite signs.05-12-2011
20080278005Uninterruptible power supply and method for implementing said power supply - An uninterruptible power supply comprising: 11-13-2008
