Abstract
This contribution provides, by means of a simple, applied example, a quick recapitulation of the conversion matrix-related theory behind the stability analysis of electronic circuits under large-signal, periodic excitations. In particular, it is recalled that some level of approximation is inherent to the conversion matrix representation of the circuit as soon as a finite harmonic order is assumed. However, better and better accuracy of the representation (and therefore reliability of the tests based on that) ensues with increasing the harmonic order. On the other hand, it is shown that purposely neglecting the trans-frequential elements of the conversion matrix representation is not justified and leads in general to unreliable results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
