A model is constructed to describe the current-voltage characteristics of phase-slip centers, taking into account the heat generated by the nonequilibrium quasiparticle current and the oscillating supercurrent. If the temperature rise is sufficient to reach T/sub c/, the description can be continued with the model of a normal hot spot between superconducting regions. Additional Joule heat is generated inside the supercconductor due to the charge imbalance at the normal-superconducting boundaries. Analytical results in the limit of small heating are presented. A numerical solution generates current-voltage characteristics observed experimentally. The results obtained with the model differ in a qualitative and in a quantitative way from those found previously by Skocpol, Beasley, and Tinkham. A comparison with experimental results on tin and aluminum microstrips is made.
