Abstract
Multilevel converters have emerged as the state of
the art high power conversion for applications in reversible
power flow. Electric power could be tapped from or injected to
the grid regardless of the discrepancies in voltage levels,
frequency, phase number and different modes of operation of the
grid and the system. This paper presents an overview of different
topologies of multilevel converters and modulation strategies
with a verification of back-to-back neutral point converter for bidirectional
power flow application
