  This paper proposes a novel multilevel inverter for automotive applications.
The topology consists of a modular DCDC converter and a tap selector, where the
DC-DC converter provides several DC-output levels and the tap selector produces
an AC signal by choosing different DC-output signals from the DC-DC converter.
To produce the DC-levels, the DC-DC converter consists of a modular structure
where the modules are connected in series. The novelty is that the modules are
connected both, magnetically in the AC-domain and electrically in the DCdomain.
Due to the usage of low power switches in the modules, the proposed structure
provides high efficiency. Furthermore, the DC-DC converter is capable of
self-balancing its modules and thus does not require large capacitors which
yields a high power density. A prototype of the proposed converter is built and
simulation, as well as experimental results, are used to verify the findings.
