Abstract:
Three-phase four-leg voltage source inverters (VSIs) are widely used in distributed power generation applications, three-phase UPS systems and fault-mode operation of a balanced three-phase system where the balanced three-phase voltage output is required when the loads are unbalanced. A three-dimensional space vector modulation (3-D SVM) switching scheme, which is proved to be compatible with modern DSP implementation for a four-leg VSI, has the advantage of higher DC link utilization, less harmonic contents and less switching losses compared with sinusoidal PWM. Therefore it is the first choi

Abstract:
A method for high performance output voltage control of a four-leg inverter based three-phase transformerless UPS is proposed. Voltage control loop is employed and the method employs stationary frame resonant filter controllers for the fundamental and harmonic frequency components. A capacitor current feedback loop provides active damping and enhances the output voltage dynamic performance. The controller design and implementation details are given. Linear and nonlinear loads for balanced and unbalanced load operating conditions are considered. The steadystate and dynamic performance of the UP

Abstract:
This thesis deals with control of three phase inverter as three phase sinusoidal voltage source for UPS application. Thesis is split to two parts, teoretical and practical. Teoretical part deals with three phase inverter topology analysis according requirement of neutral line wire and possibilities of generating sinusoidal PWM in depend of topology. There are also analysed properties of contorled system and designed 3 regulation methods with simulations. Second part of thesis deals with realisation of sinusoidal power source with inverter borrowed by Elcom company. To inverter control is used

Abstract:
This dissertation studies modeling and control issues of parallel three-phase pulse-width modulated (PWM) converters. The converters include three-phase boost rectifiers, voltage source inverters, buck rectifiers and current source inverters. The averaging of the parallel converters is performed based on a generic functional switching unit, which is called a phase leg in boost rectifiers and voltage source inverters, and a rail arm in buck rectifiers and current source inverters. Based on phase-leg and rail-arm averaging, the developed models are not only equivalent to the conventional three-p

Abstract:
碩士<br>清雲科技大學<br>電機工程研究所<br>96<br>Generally,the traditional three-phase three-leg DC-to-AC power inverter are used widely with three phase balanced loads. But, when the three-phase loads are unbalanced, that three phase voltage outputs can not be symmetrical. In this paper presents a three-phase four-leg DC-to-AC power inverter can be supply a midpoint to three phase unbalanced loads.So the three-phase four-leg DC-to-AC power inverter outputs three phase symmetrical voltages. Using symmetrical model analysises three-phase four-leg DC-to-AC power inverter how it suppresses the unbalanced loads.

碩士<br>國立臺灣科技大學<br>電機工程系<br>97<br>The thesis is concerned with the analysis and development of six-leg three-phase inverter for permanent-magnet synchronous motor(PMSM) drives. The power circuit uses six-leg three-phase inverter. Connecting each winding to two separately controlling legs yields three phase dc-ac converter. The inverter control strategy uses unipolar voltage switching method to raise the utilization factor of dc-link voltage. When a winding of three-phase PMSM breaks down, the associated load may have to be reduced to retain continuous running and increase the reliability of the
