Rm. Bass et al., AVERAGE MODELING OF CURRENT-MODE CONTROLLED CONVERTERS - INSTABILITY PREDICTIONS, International journal of electronics, 77(5), 1994, pp. 613-628
A stable DC-DC converter example is presented for which conventional a
verage models predict instability. It is shown that the formalism of v
ariable structure system theory provides a systematic procedure for de
riving an average model which does not suffer this limitation. The new
and conventional models are compared.
