| Summary: | The development of numerous consumer and industrial dc electronic products has resulted in a large demand for ac-dc rectifier type interfacing to the utility. Passive rectifiers comprise the majority of single phase interfaces in use today. The use of the conventional rectifier results in performance much less than desirable, and soon its use will be restricted by harmonic standards. The widespread use of rectifiers and poor quality of power transfer in the conventional rectifier demands attention. This thesis focuses on power factor correction and harmonic elimination techniques for the single phase rectifier. Common passive and two active power factor correction techniques are analyzed and discussed to study the effect of power factor correction and the need for improvement. The proposed ac-dc converter provides bidirectional power flow capability and reduction of high order harmonics at near unity power factor. The proposed single phase to three phase converter also provides bidirectional power flow for variable frequency, variable voltage, three phase output at near unity power factor. A thorough mathematical modeling of each converter is given, and simulation results demonstrate the power factor correction technique. A per unit design procedure for each converter is given in detail, and the designs are compared to weigh the benefits of each design. Selected experimental results and hardware concerns are discussed to validate the power factor correction converters. Finally, a new approach to calculate losses in pulse width modulated converters is also developed to accurately estimate the additional losses introduced by active means. |
