We consider in this paper a system of equations modelling a quasi-stationary induction heating process. Existence of a solution is obtained in Sobolev spaces using estimations in L∞-norm. Using a truncation technique, we build a sequence of truncated problems the solutions of which converge to a solution of the initial unbounded coefficient problem.
