The evolutionary models of SV Cen are recalculated by revising the evolutionary program to enable proper treatment for the contact stages. Features such as the rate of mass transfer, degree of contact and the positions of both components in the H-R diagram are reproduced with the initial masses of 13.4 and 7.0 solar masses for the component stars. This indicates that the binary system SV Cen is in the rapid phase of the mass transfer preceeding the reversal of the mass ratio. The mass transfer rate suddenly turns to decrease as soon as the system evolves into the contact phase, dropping to a minimum rate. In the contact phase the radius of the primary component remains almost unchanged, the secondary component slowly increases its radius, and the degree of contact increases.
