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.
