Abstract: The lack of three phase supply is becoming a major problem in many countries. With the ever-increasing number of 3 phase supply need for various operation so conversion of single phase supply to three phase supply is must, In the past, single-phase to three-phase conversion systems were made possible by the connection of passive elements capacitors and reactors with autotransformer converters. Such kind of system presents well know disadvantages and limitations. so to overcome from this disadvantages the newly adopted thyristors and power electronics devices were used mainly thyristors like SCRs, MOSFETs, GTOs etc. The project is about ‘single phase to three phase conversion system using IGBTs. Since the beginning of the solid state power electronics, the semiconductor devices were the major technology used to drive the power processors. Looking at the semiconductor devices used in the former controlled rectifiers and comparing them with the new technologies it makes possible to figure out the astonishing development. Beyond the improvement related to power switches, it was also identified a great activity in terms of the circuit topology innovations in the field of three-phase to three-phase, single- phase to single phase and three-phase to single- phase conversion systems. The single-phase induction motor drives by the three-phase induction motor drives in some low-power industrial applications. In the various industrial applications the induction motor is mostly used. The loads on induction motor always vary as per its application but speed of induction motor is constant & can not match with the load demand. If load on induction motor decrease, the speed of induction motor can not be decreases as per the load. Hence it takes rated power from supply so the energy consume by the motor is same. Hence there is energy consumption is same during load varying condition also. To overcome this problem a VFD is used in industrial application to save the energy consumption and electricity billing. Variable frequency drive (VFD) usage has increased dramatically in industrial applications. The VFDs are now commonly (VFD). This device uses power electronics to vary the frequency of input power to the motor, thereby controlling motor speed. Over the years, three-phase motors, more than single phase motors have been the main consideration in industries due to certain parameters such as; efficiency, torque ripples and power factor. In rural areas, in order to operate machine tools and rolling mills as well as in low power industrial application for robotics, where a three phase utility may not be available, high-performance converters are typically used to run the three-phase motor drives. Low losses and cost effectiveness are the very important properties for these converters various single-phase to three-phase converters have been proposed with at least 6 switches. An alternative for the reduction of losses in these converters is that the number of power switches is reduced. Many components-minimized structures are proposed in literatures. Pulse Width Modulated (PWM) inverter systems are used in a wide variety of applications as a front-end power- conditioning unit in electric drives, uninterruptible power supplies, high voltage DC transmission, Active power filters, reactive power compensators in power systems, Electric vehicles, Alternate energy systems and Industrial processes. The inverters realize dc-to-ac power conversion and in the most commonly used voltage source inverter configuration. The dc-input voltage can be obtained from a diode rectifier or from another dc source such as a battery. A typical voltage source PWM inverter system consists of rectifier, DC-link, PWM inverter along with associated control circuit and the load. Most modern voltage source inverters are controlled using a wide variety of pulse width modulation schemes, to obtain output ac voltages of the desired magnitude and frequency shaped as closely as possible to a since wave. Analysis of PWM inverter system is required to determine the input-output characteristics for an application specific design, which is used in the development and implementation of the appropriate control algorithm. Three different topologies have been proposed for multilevel inverters: diode-clamped (neutral-clamped) capacitor- clamped (flying capacitors) and cascaded multi cell with separate dc sources. In addition, several modulation and control strategies have been developed or adopted for multilevel inverters including the following: multilevel sinusoidal pulse width modulation (PWM), multilevel selective harmonic elimination, and space-vector modulation (SVM)
