evidently also provides compliance to the considered Class B (CISPR 11) EMI standards, the main advantages of the USMC compared to the B6-VSI is its potential for reducing the volume of the passive components and the sinusoidal input currents. Due to its multiple intrinsic limitations, the MC does not seem to be the appropriate topology for a general purpose, flexibly configurable, bidirectional, low-voltage ac-ac converter. For such requirements, the VLBBC clearly is the preferred choice. In conclusion, in the low-voltage and low-power ac-ac converter segment the MC technology is rather restricted to niche -applications.
