This paper presents the design and implementation of Inverter system for driving three phase Induction motor using DSPACE DS1104 controller with the controlling objective space vector pulse width modulation (SVPWM) technique. AC motor drives are commonly used over DC motor drives because of their more advantages. Induction motor is the most commonly used AC motor drive for various industrial and domestic applications. The project will be commenced by a basic understanding of SVPWM inverter, components used in the design and study the mathematical equations of the Induction motor. The performance of SVPWM based Induction motor (IM) in open loop is presented with simulation. Here the hardware implementation of the three phase inverter which is fed to a three phase induction motor driven by DSPACE CP1104 is been implemented.

The significance of Elementary Positive Output Super-Lift Luo Converter (EPOSLLC) in constant Voltage/Hertz (V/f) controlled Induction Motor (IM) drive is presented. The traditional IM drive which integrates phase controlled rectifier or boost converter in the facade end upshot tribulations like DC link fluctuations and deprived DC link voltage level. To overcome the problem, the conventional DC-DC converter is replaced with Proportional plus Integral (PI) controlled EPOSLLC in the front end of IM drive that produce the DC link voltage in geometric progression. The Voltage Source Inverter (VSI) of the suggested system renders both open loop and closed loop V/f control scheme for IM by feedback regulated Sinusoidal Pulse Width Modulation (SPWM) technique. Simulation and experimental works are conceded and results presented to demonstrate the viability of the proposed approach. Simulation is carried out using MATLAB /SIMULINK software and the experimental setup is built with Field Programmable Gate Array (FPGA) Spartan-6 processor. The anticipated EPOSLLC is found fit for V/f controlled IM drives considering the DC link Voltage, Speed response of IM and Total Harmonic Distorion (THD) in IM current.

<p class="Abstract">Due to their better DC bus utilization and easier digital realization, Space Vector Pulse Width Modulation (SVPWM) scheme is the most widely used PWM scheme. Also two level inverter is the traditional frequency converter because it has fewer components and is lower complex to control, but on the other hand it generates higher harmonic distortion. This paper presents the realization of novel SVPWM approaches applied to the three phase induction motor drives. Specifically various schemes are based on using more combinations of step operation in each cycle to approximate the reference vector, such as 24 and 48 step operations in each cycle. The basic principle of conventional SVPWM with different modulation index M is presented. The switching sequences of new approaches are described. The modulation signals waveforms, DC bus voltage utilization, De-rated motor torque, standard error of average torque, voltage and current harmonic of new approaches are analyzed by the MATLAB/SIMULINK software. The results confirms that 48 step SVPWM approach is the best compared to other approaches.</p>

Abstract This paper proposes the use of a frequency converter used in the AC motor drives to build a fast charging battery converter for electric vehicles (EV). The possibility of using semiconductor integrated modules with two-level inverters and diode rectifiers for the construction of high power voltage DC/DC converters has been demonstrated. The DC voltage of the EV battery during charging is obtained by rectifying the three-phase voltage of the PWM inverter. A 600 V DC microgrid was used to power the inverter. Simulation tests of the DC/DC converter model were carried out. The results of simulation tests were verified experimentally on a laboratory stand.

Now days, induction motor drives are used in home appliances and industries for various applications. These machines typically have low efficiencies and need high maintenance for continuous process. Hence, it is necessary to fault diagnose and test the motor for its efficiency with different parameters. The fault controller unit is designed by using Genetic Algorithm for the optimum selection of switching pulses in Space Vector Pulse Width Modulation to the supply input of IGBT(Insulated Gate Bipolar Transistor) inverter. The proposed design technique is modeled and verified using Matlab Simulink as one of the effective motor controller for maintaining the constant speed of the motor.
