| Abstract |
A way to achieve a multilevel converter using two
standard three-phase two-level inverters is presented in this
paper. In order to obtain the typical multilevel voltage
waveforms it is necessary to synchronize the commutations of the
two inverters by a proper modulation strategy. Two modulation
strategies are presented: the first one allows only generating the
characteristic multilevel line-to-line voltages; the second one
allows controlling the power flows from the two inverters too.
The proposed converter topology can be applied in the
automotive and naval fields. |
