Abstract
A converter to supply an AC voltage on a modulated signal output, having 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 the first switched state, and for each switching unit, a second switch connected between the switching output and the modulated signal output to activate that switching unit, and a third switch connected between the input of that switching unit and the modulated signal output. The converter may be a part of an uninterruptible power supply.
