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