Abstract
Se describe una red de acoplamiento de impedancia y de filtro. La red realiza dos transformaciones de impedancia previamente seleccionados y proporciona una función filtradora para atenuar la armónica eléctrica aplicada en una entrada de la red. La red convenientemente se puede estructurar en la forma de filtros dobles balanceados, los cuales son referenciados con una tierra virtual entre ellos, conectandose la tierra virtual con un protector que rodea a los componentes eléctricos. La red es particularmente adecuada para utlizarse con lámparas de descarga sin electrodo, para proporcionar una función de acoplamiento de impedancia para la bobina de inducción y para limitar la interferencia de radiofrecuencia.An impedance and filter coupling network is described. The network performs two previously selected impedance transformations and provides a filtering function to attenuate the applied electrical harmonic at a network input. The network can be conveniently structured in the form of double balanced filters, which are referenced with a virtual earth between them, connecting the virtual earth with a protector that surrounds the electrical components. The network is particularly suitable for use with electrodeless discharge lamps, to provide an impedance matching function for the induction coil, and to limit radio frequency interference.
