Abstract in different language:	Recent developments in domestic induction heating, such as the increase of the cooktop surface flexibility, lead to the design of new multi-output topologies. Those topologies enable the use of several modulation strategies that have to be considered in order to ensure high efficiency while achieving a satisfactory user experience. This paper presents a power losses model of a multiple-output ZVS resonant inverter in order to evaluate the different modulation strategies. This comparison is not only performed from the overall efficiency point of view, but also, considering the discrete losses of each of the power devices. The simulation results have been validated by means of an experimental 3600-W prototype with three induction heating coils of 2000-W rated power.
