Title: Behavior modeling of DC/DC buck converter
Keywords: hardware description language, VHDL-AMS, dc-dc converter, behavior modeling, system design
Abstract: In this paper the implementation of analog extensions of Hardware Description Languages for behavior modeling and simulations of DC/DC converters is described. The design sequence from high level model to block level is examined. The system like description and top-down methodology are considered for behavior verification. The DC/DC converter was considered as entire system, so mathematical equations can be used to model the behavior of its functionality. This will represent the high level behavior model of the circuit. This model gives the ability to analyze functionality of the system on high level assuming different control techniques and characteristics. Particularly the buck converter was examined as it is widely used and with known structure. Hardware description language model reduces simulation time and initial design efforts.
