RE: SSTC transformers

The voltage rating of the IGBTs is for when the devices are turned off.
When the devices are turned on, there is virtually zero volts across
the device. But yes, you could use 2000V rail-to-rail voltage with an
h-bridge made of 1000V IGBTs, however there would be no margin.

Also, assuming you mean GDT transformers, you'll have to wind your own.
Most commercial off-the-shelf GDTs have too much leakage inductance to
be
useful for SSTC use.

In an H-Drive configuration, two semiconductors are in series with
the load at all times.  Could you then supply the drive with twice
the voltage that a single semiconductor could handle (ex. Drive made
of 1000V IGBT's supplied with 2000V).  Also, where is a good place to
find a transformer for an SSTC coil?
