摘要

ELECTRICAL CONVERSION DEVICE, CONVERTER AND UNINTERRUPTIBLE ELECTRIC POWER SUPPLY COMPRISING ONE SUCH DEVICE A DC voltage (Vin) conversion device (51) comprising: first conversion means (2), - transformation means (4) connected to the first conversion means, and superposition and rectifying means (52) connected to the first conversion means and to the transformation means, supplying an output voltage (Voutl) comprising pulses having equal amplitudes to the sum of the amplitudes of the pulses of the primary and the secondary pulsed voltage (VI, V2). A converter (105) for converting a DC voltage (Vin) into AC voltage (Vout2) comprising the DC voltage conversion device (51), filtering means being connected on output of the superposition and rectifying means (52) of said conversion device (51). An uninterruptible electric power supply comprising a converter (105) for converting a DC voltage (Vin) into AC voltage connected to storing means, said converter comprising the DC voltage (Vin) conversion device (51) to convert the DC voltage of said storing means.
