Peak current-mode (PCM) control of pulsewidth-modulated (PWM) dc-dc converters is highly desired for its fast dynamic response and automatic overload protection. Dynamic characterization of PCM converters is mainly conducted via average-value modeling. However, deriving the average-value models of PCM converters is challenging when the component parasitics and different conduction modes are considered. This paper extends a recently developed computer-aided methodology to the PCM converters and presents an accurate dynamic average-value model that considers the parasitics and true averages of nonlinear waveforms. The proposed model is functional in all operational modes and is validated in large-signal transient studies and small-signal characterizations.
