Baiju College of Engineering, Trivandrum, India biji @ece.cet.ac.in, [email protected] Abstract—A Space Vector based Pulse Density Modulation The motivation for adopting the principle of Pulse Density scheme for spreading the spectra of Voltage Source Inverters is Modulation in the case of two level inverter is that all proposed in this paper. The proposed scheme employs first order switching converters can be considered as analog-to-digital Sigma-Delta Modulator. The principle of Vector Quantization is converters [10]–[12]. Switching converters output are discrete applied for quantizing the reference voltage Space Vector in the digital signal which is equivalent to the quantized analog Sigma Delta Modulator. For the spatial quantization, the inverter reference input. Sigma Delta Modulators are used in over voltage vector space is divided into seven Voronoi regions. In this sampling analog-to-digital converters to reduce quantization paper, a method is proposed to code these Voronoi regions using noise by spreading the spectra of the quantization noise [13]– instantaneous reference phase amplitudes without using lookup [14]. Of the different Pulse Density Modulation schemes, table. To avoid fractional arithmetic sixty degree coordinate Sigma-Delta Modulator is the minimum distortion scheme system is used. The proposed scheme automatically selects the apex vectors in the over-modulation condition and hence results [15]. Sigma-Delta Modulation with scalar quantizer has been in a smooth transition from linear to over-modulation region. In applied to two-level inverters for power control [15]–[20]. Pulse Density Modulation, the switching frequency varies Hexagonal quantizer can also be used in Sigma-Delta randomly, resulting in the spreading of harmonic spectra. The Modulator to control the Voltage Source Inverters [10]–[12], proposed scheme uses only instantaneous reference phase The concept of Vector Quantization is used instead of scalar amplitudes to obtain switching vectors without using lookup table quantization for efficient quantizing in digital communication and timer.

The adjustable speed drives, based on Inverter fed Induction Motors have become popular which need efficient II. PRINCIPLES OF SIGMA-DELTA MODULATION AND control of both frequency and voltage. In Pulse Width Modulated (PWM) inverters, frequency and voltage control is VECTOR QUANTIZATION achieved by varying the duty ratio of inverter switches [1]-[3]. Sigma-Delta Modulators are widely used in over-sampling The PWM schemes with constant switching frequency will Analog-to-Digital Converters (ADC) to reduce quantization generate prominent harmonic clusters in the output of voltage noise. The principle of Vector Quantization utilized in image and current spectra [3]-[4]. The output frequency spectra of and audio compression for efficient quantization. This paper inverter will determine the electromagnetic interference emitted uses the principle of Sigma-Delta Modulation to control the by inverters and acoustic noise generated by electric machine inverters and the principle of Vector Quantization to realize the driven by the inverters [3]-[9]. In Random Pulse Width quantizer in Sigma-Delta Modulator. Basic principles of Modulation techniques, the switching frequency is varied Sigma-Delta Modulation and Vector Quantization are randomly to spread the voltage and current harmonics over a described in this section. wide frequency range without affecting the fundamental A. First Order Sigma-Delta Modulator frequency component [5]-[7]. The Switching frequency modulation techniques can be classified into three types: Block diagram of a first order sigma-delta modulator is periodic, randomized and chaotic [6]. Variable switching shown in Fig. 1 [15]. The modulator consists of a difference frequency PWM schemes require precise timing calculation node (delta), a discrete time integrator (sigma), a quantizer in with the help of high performance DSP processor for pulse forward path and a digital-to-analog converter (DAC) in the pattern generation. feedback path. To simplify the analysis, the quantizer is often linearised and modeled by a quantization noise source e[n], In this paper, a Pulse Density Modulation scheme, with added to the integrated error signal y[n], to produce the variable switching frequency similar to that used in the case of quantized output signal s[n] = y[n] + e[n]. analog-to-digital converters, is proposed for two level inverters. 978-1-4244-8756-1/11/$26.00 c 2011 IEEE 1227 The corresponding time domain version of the modulator output is s[n] = v[n-1] + e[n] – e[n-1]. That is the output of sigma delta modulator consists of input signal delayed by one sampling clock period v[n-1] and first order differentiation of quantization noise e[n] – e[n-1]. Therefore the input signal passes through the system unaffected and the quantization noise is high pass filtered by the differentiator thus increasing the signal-to-noise ratio (SNR) in the frequency band of interest. B. Vector Quantization In the proposed scheme, principle of Vector Quantization is used to implement quantizer in the Sigma–Delta Modulator. The Vector Quantizer maps k-dimensional vectors in the vector k space R into a finite set of vectors Y = {yi: i = 1, 2, ..., N}. Each vector yi is called a code vector or a codeword, and the set of all the codewords is called a codebook. Associated Fig. 2. Proposed Vector Quantized Space Vector Pulse Density with each codeword, yi, is a nearest neighbour region called Modulator Voronoi region, and it is defined by: = { ∈ k − ≤ − ≠ } Vi x R :|| x yi || || x y j ||, for all j i Each codeword resides in its own Voronoi region. In space vector modulation schemes, the input reference space vector is realised by switching the discrete inverter voltage levels. The switching converter output are at discrete levels which are equivalent to the quantized analog reference input. The switching converters can be therefore considered as Analog to Digital Converters. Sigma-Delta Analog to Digital Converter is used to quantize the reference space vector in the present work. Difference between the reference space vector and modulator output vector generate an error space vector. The error space vector is random in nature with varying Fig. 3.

Although the data to be transmitted is digital, the telephone channel is designed to carry voice signals having a bandwidth of approximately 300 to 3300Hz. The telephone transmission channel suffers from delay distortion, noise, crosstalk, impedance mismatches, near-end and far-end echoes, and other imperfections. While certain levels of these signal degradations are perfectly acceptable for voice communication, they can cause high error rates in digital data transmission. The fundamental purpose of the transmitter portion of the modem is to prepare the digital data for transmission over the analog voice line. The purpose of the receiver portion of the modem is to receive the signal which contains the analog representation of the data , and reconstruct the original digital data at an acceptable error rate. High performance modems make use of digital techniques to perform such functions as modulation, demodulation, error detection and correction, equalization, and echo cancellation.

III Abstract For years, DSP has been the dominant tool in implementing gate switching for power inverter. It is a powerful and reliable technology in carrying out complex switching schemes. DSP is still expensive due to its intensive use of resource in chip fabrication. There is no flexibility in making change on hardware once a DSP chip is selected. It is also time consuming in a design development because the learning curve of the DSP is stiff. Recently, a new approach to the problem has emerged. It is called embedded system design. Basically, it is a FPGA system combined with a RISC type microprocessor.
