Abstract

The switch model of pulsewidth modulation (PWM) converters proposed by V. Vorperian (ibid., vol.26, p.490-496, 497-505, May 1990) is critically examined. The commenter suggests that the omission of the inductor from the model has led to errors in the modeling of discontinuous conduction mode (DCM) converters. The author responds that intuitive conflicts with the average switch model can easily arise if the expressions and derivations are examined outside the context and approximations of average modeling. He offers an explanation of the points raised by commenter
