A neutral point voltage balancing method for multi-level GTO inverters
(
IEEE
, 2006 , Conference Paper)
The balancing problem of the DC-link capacitor voltage is inherent in the NPC inverter. It is extremely important to keep the upper and lower DC-link capacitor voltages balanced to guarantee the three level operation of ...
A novel multilevel carrier-based PWM-control method for GTO inverter in low index modulation region
(
IEEE
, 2006 , Article)
Gate turn offs (GTOs) have an inherent minimum ON-OFF time, which is needed for their safe operation. For GTO-based three-level or neutral-point-clamped (NPC) inverters, this minimum ON-OFF pulsewidth limitation results ...
