modified ATX (current mode)

Hi!
The attached file is a modified schematic of ATX power supply which I want to use as current mode supply. So the output current from current sense transformer was used at Pin4 (Deadtime Control) of IC TL494, through variable resistor to adjust the desired current (9A). Please comment if this technique can deliver a constant current output. Voltage regulation is not necessary.

Regards
