| Abstract |
This paper introduces a new ac/ac multilevel
converter for a single-phase inverter with HF isolation and
bidirectional power flow capability. The advantage is to provide
compact HF isolation, without an additional DC stage and with
lower harmonic distortion in the load. Higher efficiency and
better dynamic response are possible as well . The topology is
based on a HF inverter, a HF transformer and the new ac/ac
multilevel converter. A modulation strategy for the commutation
of the ac/ac converter switches is presented.
Synthesis, simulation and experimental results of the
multilevel converter are presented. |
