Abstract :
The paper describes operation of three-level inverters with synchronized pulsewidth modulation (PWM) at control regimes different from standard volts/hertz control. Control algorithms provide common-mode voltage cancellation in three-phase load in this case. The output voltage of converters has quarter-wave symmetry during the whole control range including the zone of overmodulation. Simulations give the behaviour of different versions of synchronous PWM.
