“…This technique generates reference three-phase signals by sharing the space vector among the active and zero vectors such that the harmonic content is optimized. The maximum inverter line-to-line voltage generated by the SVPWM scheme is 15.5% higher than that of the SPWM for a given DC bus voltage [17,18].…”

The drop in DC-link voltage of adjustable speed drives (ASD) occurs mainly due to the increase in output power demands. This may lead to inefficient operation and eventually the tripping of the drive. This paper presents a Double Space Vector Pulse Width Modulation (DSVPWM) technique for boosting and compensating the DC-link voltage of Z-source inverter (ZSI). The DSVPWM technique estimates the required shoot through period of the Z-source inverter to maintain the DC-link voltage constant at the desired level through capacitor voltage control. The DSVPWM can obtain maximum boost at any given modulation index in comparison to simple boost control (SBC) method. It also utilizes the dead time more effectively. The speed control of the ZSI fed induction motor drive is done by employing indirect field-oriented (IFO) control method. A 32-bit DSP (TMS320F28335) is used to implement the IFOC-DSVPWM method for ZSI. The power structure and the modulation technique are well suited for electric vehicle application. DSP or microcontroller as a control system for the power converter. Selection of electrical (traction) motors for propulsion systems is a very important step that requires special attention. In fact, the automotive industry is still seeking for the most appropriate electric propulsion system for EV. In this case, key issues are efficiency, torque density, weight, cost, cooling, maximum speed, fault-tolerance, safety, and reliability. The types of electric motors adapted for electric vehicles are DC motor, the induction motor, the permanent magnet synchronous motor, and the switched reluctance motor. Of late, the cage induction motors are accepted as the most suitable motors for the electric propulsion of EVs owing to their reliability, ruggedness, low maintenance, low cost, and ability to operate in inimical environments. They are particularly well suited for industrial and traction drive environments. Today, induction motor drive is the most mature technology among various commutatorless motor drives. The high performance control of induction motors can decouple its torque and field control [3,4].In a voltage source inverter fed induction motor for an EV, the speed control techniques are scalar control ( / ), indirect field-oriented control (IFOC), and direct torque

In this paper, the authors treat one of the major problems noted in the association of electrical motors fed by the inverters, it is well known as the acoustic and vibratory noise. An electrical propulsion system mainly based on a Doubly Fed Induction Machine (DFIM), operating in motor mode and supplied by two Voltage Source Inverters (VSIs) is introduced. The modeling of the marine propeller is reported and the equations defining its behavior are established. A Stator Flux Oriented Control (SFOC) associated to different modulators (PWM) is chosen to control the system. These control methods are applied considering taking into considerations a real naval propulsion operating cycle. In order to choose the optimal law in term of acoustic noise, these laws are evaluated during a cruise cycle.

“…In general, two's complement data representation is used in processors and is an efficient way of representing signed numbers in Mitra (2001), Parhi (1999) and Pongiannan et al (2011). The most commonly used type of data formats are: (i) Fixed point representation (FXPR) in Oberstar (2007), and (ii) floating point representation (FLPR) in IEEE Standard (2008).…”

This paper first presents a review of very large scale integration signal processing applications using Q-format data representation, through field programmable gate arrays. Also, this paper presents a comprehensive review of Q-formatbased applications, which include arithmetic computations in signal processing, linear time-invariant systems, finite impulse response filter, 3-D graphics system, personal digital assistant, and neural networks and power electronic converter control are discussed. Finally, a Q-format-based arithmetic logic unit (QALU) has been designed and developed using very high speed integrated circuit hardware description language. The QALU is used to develop the space vector pulse width modulation control, and the simulation and experimental results are presented.
