“…Since these are generally for medium to high voltages (10 kV and above), it is principally the series connection which comes into consideration. Inverters of 100 MW have already been realised using first generation IGCTs in direct series connection [Steimer et al,5], albeit at line frequency. Today, 5 MW IGCT inverters operating directly on the 4160 V MV line, without snubbers or series connection, are entering commercial service at 500 -1000 Hz pwm.…”

“…These modifications will increase the losses and reduce the dynamic performance, so a system with fewer GTOs connected in series provides better voltage sharing, and improves efficiency and dynamic performance [51]. Recently, however, the technology that allows the robust, reliable and cost-efficient series connection of GTOs is industrially mature [100]. Especially, in [102] , with a digital control circuit for extremely accurate adjustment of gate turn-off timing in units of 0.1 μs, the up to 16 GTOs connected in series shared the voltage uniformly in the turn-off period.…”
