Conmutación en inversores resonantes paralelos para altas frecuencias.

An analysis of the conmutation processes in different modes of operation (inductive, capacitive and resistive) of the paralell-resonant inverters is presented in this paper. First the ideal and real behaviours of its semiconductor components are considered and the iddle components are excluded. Also the modes of operation corresponding to the proper MOSFET transistors trigger angle are analyzed. Second, the case in which the value of idle inductances of the circuit cannot be neglectable is considered, analysing also why are not commendable in this conditions the common conmutation strategies. A calculation strategy for proper moment of the transistors' triggering which provides a sure opperation in any working instant of the inverter circuit in optimum commutation mode is verified. Several simmulations that confirms the results validity using ORCAD software, are performed. [ABSTRACT FROM AUTHOR]
