of a transformerless grid-connected converter was proposed. This solution relies on an active common-mode filter connected at the output of the power converter. It is constituted by a common-mode transformer properly supplied by an additional low-power full-bridge.
The proposed solution is applicable to both stand-alone and grid-connected con-verters. In particular in this work the active filter was applied to a full-bridge power converter topology driven by the efficient 3-level (unipolar) PWM.
The feasibility of the proposed solution and the capacity to operate with power factor different from one was proven through extensive simulations in Simulink/Plecs environment, and confirmed with experimental results.
On this purpose, a converter prototype was designed and built. It embeds all the components for enabling the connection to the mains in accordance to the Italian legislation CEI 0-21.
The experimental results were in accordance with the simulations. In particular, in real converters slight variations in the total common-mode voltage are introduced by the dead time intervals of the PWM modulation strategy. For this reason a dead-time compensation strategy able to minimize the vcm variations, and therefore the common-mode current was elaborated.
Simple design guidelines for the active common-mode filter were presented in order to minimize the size of passive components and in particular the core of the common-mode transformer employed.
A fair comparison with the state of the art was elaborated for the proposed solu-tion in terms of number of power devices employed, efficiency and reliability.
It was highlighted that the proposed solution requires four additional power swit-ches with respect to a full-bridge solar inverter, but as they need to provide only the magnetizing current of the common-mode transformer, the additional losses resulted to be very low. In particular, in the prototype the additional power losses introduced by the active common-mode filter resulted equal to 4 W compared to 2000 VA of in-jected power. It is important to put in evidence that only standard and low-cost power switches were used in the laboratory prototype. With a more accurate choice of the power devices, employing SiC or GaN devices, the power losses could be even lower.
Furthermore, it is also possible to oversize, without a significant increase of co-st, the power size of the 4 additional power switches in order to avoid an overall reliability reduction of the power converter due to the increased number of power switches.
