“…There have been several control strategies developed to enhance the fundamental component and minimizing the total harmonics distortion (THD) through elimination of lower order harmonics and to create a wider dead band for a given switching frequency [1–3]. Several attempts have been made in the last few decades to develop PWM schemes that differ in their concept and performance [4–8]. In 1999, an analog-based modified PWM control scheme has been developed to eliminate low order harmonic components caused by the nonconstant dc voltage [9].…”

This paper corroborates three different hybrid modulation strategies suitable for single-phase voltage source inverter. The proposed method is formulated using fundamental switching and carrier based pulse width modulation methods. The main tale of this proposed method is to optimize a specific performance criterion, such as minimization of the total harmonic distortion (THD), lower order harmonics, switching losses, and heat losses. The proposed method is articulated using fundamental switching and carrier based pulse width modulation methods. Thus, the harmonic pollution in the power system will be reduced and the power quality will be augmented with better harmonic profile for a target fundamental output voltage. The proposed modulation strategies are simulated in MATLAB r2010a and implemented in a Xilinx spartan 3E-500 FG 320 FPGA processor. The feasibility of these modulation strategies is authenticated through simulation and experimental results.

“…Most of the ac drives in use today were adopting either fully DSP based digital control strategy or partially FPGA and DSP as reported in [1,2,3,4]. No doubt, this arrangement has the advantages of simpler circuitry, software control and flexibility in adaptation to various applications; it suffers the disadvantages of sluggishness and limited computation resources due to the sequential computation feature, complicated design process and long development time cycle [5].…”

Abstract:In this paper, a flexible, high computation speed and cost effective field programmable gate array (FPGA)-based speed controller for an induction motor with field-oriented control, (FOC) is presented. All the control functions including the space vector modulation based PWM waveform generation, field-oriented control algorithm and rotor flux position estimation have been realized using FPGA to reduce the total part count of the hardware prototype and hence provide a low cost solution. The constructed FOC IC consists of 6844 logic elements and is realized using Cyclone, EPIC12q240C8 from Altera Inc. The sampling rate can be programmed up to 100 MHz. Experimental result is included in this paper to illustrate the performance of the designed IC, FOCIC and the feasibility of integrating of SVM and FOC on single chip.

“…6. The full design flow is an iterative process of entering, implementing, and verifying the design until it is correct and complete [6][7]. In realizing the proposed PWM Pattern generator, cost consideration led to selecting a Spartan -11 XC2SlOO-5PQ208 FPGA device from Xilinx Inc.…”

“…Secondly, a fast microprocessor is employed to calculate some parameters. However, to obtain higher switching frequency, a fast processor, such a DSP [3], [6], is necessary resulting in high cost, and also, a long time is required to develop software in a new processor structure. Moreover, processor controlled by software is not suitable for a switching power circuit, which generates a lot of noise, resulting in High-risk of collapse.…”

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.
