Uma metodologia de desenvolvimento do controle digital de conversores estáticos utilizando FPGA

Abstract

This work describes a methodology for the development of the digital control of power converters, where the whole structure – converter and control system – can be modeled in the same environment through the hardware description language VHDL-AMS. This language allows a behavioral description for the whole structure, so that the control system can be simulated, tested and validated without the need of a prototype. The portability of the VHDL language allows the implementation of the digital control code in an ASIC or FPGA. Simulations results show the feasibility of the methodology offering interesting possibilities in power converter control.
