The conventional small-signal circuit model in the discontinuous conduction mode (DCM) shows large discrepancies at high frequencies. A new unified small-signal circuit model of the pulsewidth modulation (PWM) switch including inductor in the DCM is proposed to overcome the inaccuracy of the conventional small-signal circuit model.
