| Abstract: | The large output ripple current impaired the performance of Two Transistors Forward Converter (TTFC). By the ac flux positive coupling of the inductor and transformer, the output ripple current can be reduced. The improved TTFC with integrated magnetics is proposed in this paper. The design consideration for the integrated magnetics is discussed along with the effect on the ripple currents. Two 1000W TTFC prototype converters, with integrated magnetics and without, are built to verify the operation principle |

| Keywords: | Integrated magnetics TTFC Smaller current ripple |
