Comparative study of high performance rectifiers

Harmonic pollution and low power factor in power systems caused by power converters have been a great concern. To overcome these problems several converters and control schemes have been proposed in recent years. This work is proposed to identify the power converters with low cost/small size/high efficiency for single phase and three phase systems. To study the control technique for such converters to improve the Power Factor (PF) and reduce total harmonic distortion (THD) with output voltage regulation. This work has very high potential for ups, motor drives and other industrial applications. The operation, analysis and design of various control techniques for high performance rectifiers are investigated and verified through simulation. The best converter with best control technique is built and validated practically. The verification has been extended for three phase system also.
