VHDL-AMS based design methodology of very large scale integration fully digital controller for intelligent power control

This paper presents a methodology to design very large scale integration fully digital controller for intelligent power control. Step by step, top-down methodology for virtual prototyping based on very high speed integrated circuits hardware description language-analog-mixed signal (VHDL-AMS) with associated mixed simulation tools was used to study digital adaptation and architecture implementation of the control algorithm. Modeling, mixed simulation and virtual prototyping are achieved in an unique design environment. An application using the proposed methodology was studied: a digital controller for a single-phase parallel active power filter. The controller is described and virtual prototyping examined. Analog and digital models were used to define the algorithm implementation, specific binary format and architecture. The register transfer level model for this digital controller was finally validated by mixed simulation
