I am in fact working on a half bridge induction heater using this chip. 
Suggest using either IR2153D or IR21531D .  Later part has reduced deadtime 
over former, and both with D suffix has bootstrap diode (for upper MOS 
driver) integral to chip.  Also by pulling Ct terminal down to ground 
immediately disables both outputs of chip, allowing 555 staccato 
modulation.  There is a way
to connect two chips in a "master-slave" arrangement to allow full-bridge 
operation.  Useful tune range of ~30kHz to >500kHz.  It is intended as a 
flourscent light ballast controller, however there are several circuits 
posted on IR's website as well as on the WWW that shows chip being used as 
a half-bridge power supply controller (check Pupman archives on my previous 
postings on this chip).

I believe the chip will successfully control a small (<1kW) SSTC.  With 
200mA sink/source
currents you are limited in size of FET's that can be driven, I'm 
reasonably sure that output impedance of '2153 is a litle high for IGBT's 
unless induction heating grade (like Fairchild SDH40N60UFD) is used.  I 
have a schematic of a commerical plama globe (24") using one of these chips 
with a 24-30VDC PS as the globe controller.

I posted one recently with last mods suggested by Marco Denacolai for THOR 
PS.  Check Pupman archives.  This is circuit has not been built as yet, and 
is conceptual so USE AT OWN RISK!
