D. Component Count
The number of passive components required in ZSI is 6,
whereas for CFSI and SBI, it is 4 owing to one less L-C
pair. Again, CFSI and SBI need 11 switches compared to 9
of ZSI (break-up shown in Table I). Although the total component
count remains the same for ZSI, SBI, and CFSI, due to
the elimination of passive magnetic components, CFSI leads
to a more compact design in a low-power application. The
total component count for the boost-VSI topology is one less
compared to others.
