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 ...
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 converter for sinusoidal encoders
(
IEEE
, 2006 , Conference Paper)
The paper presents a novel and low cost method for determining the angle from sine and cosine signals generated by angular position sensors such as resolvers and sinusoidal encoders. The proposed scheme is based upon the ...
