N2 - We numerically calculate total AC losses in a single Bi-2223 tape carrying a transport current in an external magnetic field parallel or perpendicular to the tape face. We also carry out the calculations for two models of three-strand parallel conductor. One is without transposition, and the other is with optimum transposition so that the branch current in each strand becomes equal. It is confirmed the total AC losses fairly increase with the simultaneous application of transport current. It is also found that in the perpendicular field the total losses are scarcely dependent on transposition but on the number of strands in the smaller field amplitude. In the parallel field, the effect of the number of strands on the total AC losses is notable as well as transposition.
