Abstract:

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

1 Introduction

Intelligent Power Control has made significant progress since the 1980's thanks to Microelectronics advanced features in digital processors [1]. Most research has focused on control strategies, Microprocessors or Digital Signal Processors (DSPs). However, with Application Specific Integrated Circuits (ASICs) and Field Programmable Gate Arrays (FPGAs) technologies, digital controller can be integrated in a single chip. Very Large Scale Integration (VLSI) can also be used for real time fully digital controller in Intelligent Power Control requiring reliability and performance, reducing the number of digital control system components and guaranteeing architecture confi-dentiality. The benefits of VLSI digital controller design are as follows:

the whole digital controller is implemented in only a single chip, consequently the circuit is very compact;

systems on VLSI chip are reliable and do not need any control software;

the use of FPGA technology when hardware prototyping allows faster design and verification time; more, design change canbe achieved without penalty.
