A SINGLE-PHASE CASCADED MULTILEVEL INVERTER
- This inverter is comprised of a series connection of
the proposed basic unit and is able to only generate positive levels at the
output.
- Therefore, an H-bridge is added to the proposed inverter. This inverter
is called the developed cascaded multilevel inverter.
- In order to generate all
voltage levels (even and odd) at the output, four different algorithms are
proposed to determine the magnitude of dc voltage sources.
- Reduction in the
number of power switches, driver circuits, and dc voltage sources is the
advantage of the developed single-phase cascaded multilevel inverter.
- As a
result, the installation space and cost of the inverter are reduced.
- These
features are obtained by the comparison of the conventional cascaded multilevel
inverters with the proposed cascaded topology.
- The ability of the proposed
inverter to generate all voltage levels (even and odd) is reconfirmed by using
the experimental results of a 15-level inverter.
