did you specify input and output voltage? 144 to 340ish? You can probably get away with 290v if you have svpwm I think, unless you want to extend the nominal speed.

edit, plugged in 144 and 290v here @ 600A 30% ripple, 5% voltage ripple:
Switching Converter Power Supplies

Code:
Item	Value	Units
Volts In	144	V
Volts Out	290	V
Load Current	600	A
Freq.	10	KHz
Vripple	14.5	V
Duty Cycle	50.638591646531	%
Ipp Inductor	180	A
Ipk Inductor	690	A
Irms	512.64022471905	A

C	2095.3899991668	uF

changed to 20khz:
