The present invention relates to an inverter topology with a DC/DC voltage boost converter, which is also scalable. The arrangement of converters and power lines used in this topology makes it possible to maximize the efficiency of the energy conversion that takes place in photovoltaic plants or in any other system based on power transmission that use DC power lines, reducing the values of current used for a given power level. The inverter includes two DC/DC converters connected in parallel to one another and two DC/AC converters connected in parallel to one another. The two DC/DC converters are connected in series with the two DC/AC converters by means of two buses consisting of three DC power lines where one of the DC power lines is common to the two buses.
