Under
the growing impetus of renewable energy policies, the number of grid-connected
domestic photovoltaic power plants will increase considerably in the coming
years. Inverters are important links because they must not penalize the energy
efficiency of the systems and the quality of the signals injected into the AC
grid must be indisputable. Transformerless multilevel inverters are well used
in grid connected home photovoltaic applications because of their ability to
generate very good waveforms, reducing switching frequency, and their low
voltage on power devices. However, this type of inverter needs to be modified
to both limit common-mode currents and improve system robustness. Neutral point
clamped topologies can certainly provide an answer to these problems, but their
electronic structure can sometimes be difficult to implement and development
costs can be important. This chapter presents a new 5-level mixed-mode inverter
that meets these challenges. The operating principle of the inverter is
proposed. Many experimental measurements, carried out at low output power, are
described to validate this new concept. In particular, the output voltage and
current as well as the total harmonic distortion of the output voltage
underline the relevance of such a structure.
