Modeling the high-frequency behavior of a fluorescent lamp: a comment on "a PSpice circuit model for low-pressure gaseous discharge lamps operating at high frequency"

The shortcomings of the model presented by Wu et al. (see ibid., vol. 44, p. 428-31, 1997) are pointed out and an improved SPICE-compatible equivalent circuit that dodges the limitations is presented. It is shown that the proposed model is useful in emulating the fluorescent lamp response to a change in excitation frequency.
