Title
Computer-Aided Average-Value Modeling of Fourth-Order PWM DC-DC Converters
Abstract
Average-value modeling of dc-dc converters has been an area of active research for many years. Developing accurate average-value models of higher-order converters is further complicated by the presence of parasitics and waveform nonlinearity. A recently proposed numerical approach has been shown to be effective in including the effect of parasitics for second-order inductor-based dc-dc converters. This paper extends the numerical state-space averaging to the fourth-order capacitor-based switching stages. The proposed model takes into account conduction losses associated with switching stage components and is seamlessly functional in all operational modes. The proposed model is validated with a hardware prototype and detailed simulation and is shown to accurately predict large-signal time-domain transients as well as small-signal frequency-domain characteristics.
