2. Abstract
• The costs of electrical energy from photovoltaic have been reduced by about 90% in the last two
decades due to improved solar cell manufacturing and PV-Inverters.
• It is shown which innovations in the field of PV-Inverters helped to reduce the costs of the
systems.
• It can also be seen, that there are new approaches needed to reduce the system costs even
further.
• The requirements on the power electronic components because of additional functions are
discussed.
• At the end of the paper it is shown how these topics will have an impact on the power electronics
of PV-Inverters in the future.

4. Proposed System
• The main aim of presentation the proposed cascaded multilevel inverter is increasing the number
of output voltage levels by using lower number of power electronic devices.
• In order to investigate the feature the proposed cascaded multilevel inverter is compared with
the conventional cascaded inverters from the amount of blocked voltage by switches, the number
of required power switches, IGBTs and dc voltage sources points of view. In these comparisons,
the proposed topology based on its two algorithms is considered.
• These algorithms are shown by 1 P and 2 P for the first and second proposed algorithms,
respectively.
• The H-bridge cascaded multilevel inverter with five different algorithms as symmetric and
asymmetric cascaded inverters are considered.
