Resumen:
This dissertation proposes converters applied to single-phase three-wire systems. Den-
of these four are DC/AC based on neutral-point clamped arms.
ped) (NPC), in which one has two arms and three have three arms - two of which are
hybrid versions. In addition, two single-phase AC/DC/AC converters are proposed for
three-wire single-phase circuits based on two-level arms (2L). Techniques are presented for
pulse width modulation (PWM) modulation and strategies
of control. Furthermore, the proposed AC/DC/AC converters are evaluated for correctness.
shared arm current, DC bus current, and DC bus voltages.
Comparisons between conventional and proposed converters are performed in terms of
harmonic distortions of the input and output voltages, and also losses in the secondary devices.
microconductors. Finally, the performance of the converters is evaluated through results of
simulation and experiments.
