Exact continuous models of Pulse Width Modulation (PWM) regulators in both continuous and discontinuous conduction modes
Abstract
A model for pulse width modulation voltageregulator dynamics in which the circuit is assumed to be a linear timevariant system, and widthmodulation action in the output filter is represented by a suitable set of impulse generators applied at each switching instant, is presented. Once the feedbackloop is open, the comb function of its characteristic response can be expressed by a recursive matrix relation; the latter is Fouriertransformed, achieving the continuous function Gloop. In the discontinuous conduction mode, the procedure directly provides an analytic expression. The model requires minimum computing resources and runs on personal computers.
