FPGA Based Implementation of Sinusoidal PWM for Induction Motor Drive Applications

The rapid advances in very large scale integration (VLSI) technology lead to implement modern high speed digital controllers with excellent performance, compared to traditional analog control systems. The field programmable gate array (FPGA) devices provide programmable system-on-chip (SoC) environments for designing powerful ASIC controllers with dedicated architectures. This paper presents a FPGA-based digital controller proposed to control induction three-phase motor drives using a single SPARTAN ٣ chip, XC٣S۴٠٠-۵I-PQ٢٠٨, from Xilinx, Inc. The sinusoidal pulse width modulation (SPWM) method is realized on FPGA to generate controlling switching pulses for insulated-gate bipolar transistors (IGBTs) in drive system implementing a Verilog hardware description language (HDL) code. The experimental and simulation results demonstrate the efficiency of FPGA-based solutions for implementing dedicated SPWM controller for induction motor drive systems.
