A System on Chip (Soc) - High-performance Power Drive Applications - SVPWM Based Voltage Source Inverter

Abstract

This paper presents a new circuit realization on single on chip for the space-vector pulse-width modulation (SVPWM) strategy. An SVPWM control integrated circuit (IC) has been developed using the state-of-the-art field-programmable gate array (FPGA) technology. The proposed SVPWM control scheme can be realized using only a single FPGA (XC4010) from Xilinx, Inc. presents the design and Implementation of library modules called Intellectual Property (IP) Cores to develop highperformance power drives and motion control applications. The Library is coded in VHDL for modularity and portability. Very frequently Power Drives and motion control applications are implemented using DSP or Microcontroller and algorithms are written in assembly or in a high level language such as ‗C.' By using VHDL to describe the circuit we implement algorithms directly in hardware instead of writing sequential programs. The realization includes the module of the implementation of Space Vector Pulse Width Modulation (SVPWM) switching patterns for three phases Voltage Source Inverters (VSI) which plays a vital role in the induction machine control. The objectives is to present a survey on the advancement recently introduced in the design of electronic circuits and to discuss how they can be implemented in Industrial Electronics industry to pace with the new wave of global competition. In this work a methodology for developing the IP cores for Power Drive and Motion Control Applications is proposed. The advantages of this implementation are to reduce the cost by embedding them in a single chip, to achieve the processing speed incomparable to that of sequential flow program of DSP's and Microprocessors, to make them application specific and they can be enhanced to suit future complex requirements.

FPGA Hardware in the Loop Validation of Asynchronous Machine with Full Direct Torque Control Implementation

“…In ref. [9] the sampling time is equal to 50 µs. However, the execution time is too long compared to the FPGA.…”

“…But these devices have a limited processing speed because of serial calculations; this affects its performance especially in real time application. The use of FPGA circuits offers an appropriate solution for fast calculations [9][10][11][12][13][14].…”

On-Line FPGA Hardware in the Loop Validation of Based Fuzzy-STPWM Induction Motor Control

“…In recent decades, rather laborious controls have been developed to perform asynchronous machine control using PWM pulse width modulation techniques [5][6][7][8]. This advance is mainly due to the evolution of microelectronics such as ASICs, microprocessors and programmable logic circuits [9][10][11] that allows complex algorithms to implement the commands of the asynchronous machine [12][13][14]. In addition, the integration of artificial intelligence techniques to improve the performance of commands is increasingly used [15,16].…”
