... are sufficient to realize this four-level inverter scheme. It is shown that it is possible to produce a voltage vector of 1-p.u. Magnitude with a total deck-line voltage of 0.66 p.u., indicating that the DC-link utilization is enhanced by a factor of 33% with this power-circuit configuration. In the ...

... High specific power density electric machines typically employ non-metallic materials instead of iron, which consequently decreases the machine’s winding inductance. Since the low reactance windings cannot effectively filter PWM voltage waveforms, we propose a flying capacitor multilevel (FCML) inve ...
