Abstract :
Controller design for six-switch pulse width modulated (PWM) voltage source rectifiers (vsrs) is often accomplished in the rotating d-q frame coordinates in order to achieve a high-performance control. In contrast, the development of a d-q Frame controller for a four-switch PWM VSR is rarely reported in the literature. . For this purpose, a mathematical model of the four-switch PWM VSR In rotating d-q frame is first derived. Its success is relied on performing a so-called “reduced Park Transformation” on switching functions. The derived model shares much structural property with that of a six-switch VSR. The modeling and design of four switch three phase PWM converter with controller performance are analyzed in this paper. The high performance control of two d-q frame current controller design based on propositional plus integral controller (LPI) is performed in this project. Their effectiveness is verified via computer simulation and hardware experiment. The performance of four switch PWM voltage source rectifier results will be compared with three phase six switch rectifier. With LPI D-Q current controller delivers nearly sinusoidal and balanced line currents and small dc bus voltage ripples. The proposed voltage source rectifier will be faicated by using MOSFET. Then, two d-q frame current controller designs, input-output feedback linearization (IOFL) and linear
