GTO Inverter for AC Traction Drives

IEEE Transactions on Industry Applications, 1983
A 600-kVA capacity GTO inverter for traction drives has been developed using 2500-V/1000-A gate turn-off (GTO) thyristors, and running tests have been carried out. To utilize the advantages of GTO thyristors, circuit inductance of both main loops and snubber loops were minimized in order to decrease overvoltage applied to GTO thyristors after turn-off.

Inverted Nipple Correction with Dermal Flaps and Traction

Aesthetic Plastic Surgery, 2014
Inverted nipple occurs when part of or the entire nipple is abnormally located below the areola. Surgical repair of severe cases involves suture or flap techniques. Complications include recurrence, lactation problems, hypopigmented scar formation in the areola, and loss of sensation.

Cascaded multilevel inverter for underground traction drives

2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012
The elementary concept of a multilevel converter to achieve medium and high voltage by using a series of power semiconductor switches with several lower voltage DC sources. A suitable modulation technique is required to perform the power conversion by synthesizing a staircase voltage waveform to reduce the Total Harmonic Distortion (THD) of the multi ...
