Power conditioners for low-voltage DC sources in Distributed Generation usually have two major functions: to boost the energy source output voltage and to convert it into an AC voltage. The voltage boost is usually done by a DC-DC converter.

The M2C generates output voltage with lower harmonic content than that for the two-level converter. Therefore, it does not require ac filters. The absence of a switching frequency component the arm current and operation -The M2C generates out
