Hi Gary,
           Does the output really have to be nice sinusoidal AC?
You could bypass the NST etc. completely if you have to resort to 
switchmode converters. Also removes a source of inefficiency in the 
chain. Step the output up directly and rectifify and use a charging 
choke. If you must resort to AC, best you can do is a PWM driven
H-bridge whose output can be directly connected to the transformer you 
wish to use with a simple blocking filter at the switching frequency.
