Could be an issue, but not necessarily. Do you see short (100ns range) and high voltage peaks at Uce, at heavy load?..but i dont have any decoupling capacitor (ex:1uF/400) to eliminate spike
I've built a half-bridge SMPS based on the sg3525 (which works at 35kHz) + tx4424 + GDT + IGBT. The end result should be a 14.4v and 200A DC power supply

An externally hosted image should be here but it was not working when we last tested it.
