Some typical applications of series resonant inverters refers to the development of power supplies for the inductive heating field. Phase shift method is of a great interest for the command of the above mentioned inverters. Concerning this command method, in the paper was developed a detailed study to determine the conditions under which the power switches commutation takes place at zero voltage (Zero Voltage Switching) (ZVS). The authors studied two different ways for the power switches command signals dephasing. For every situation were etablished the power switches having trouble switching. Also, were identified the parameters that influence the power switches commutation regime Based on ORCAD simulations were obtained the limit values of these parameters, values that delimit the non-ZVS commutation regime from the ZVS regime.
