ABSTRACT:
In
this paper the standalone operation of the modified seven-level Packed U-Cell
(MPUC) inverter is presented and
analyzed. The MPUC inverter has two DC sources and six switches, which generate
seven voltage levels at the output. Compared to cascaded H-bridge and neutral
point clamp multilevel inverters, the MPUC inverter generates a higher number
of voltage levels using fewer components. The experimental results of the MPUC
prototype validate the appropriate operation of the multilevel inverter dealing
with various load types including motor, linear, and nonlinear ones. The design
considerations, including output AC voltage RMS value, switching frequency, and
switch voltage rating, as well as the harmonic analysis of the output voltage
waveform, are taken into account to prove the advantages of the introduced
multilevel inverter.
