Boost Converter for Power Factor Correction of DC Motor Drive
With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. While the discontinuous conduction mode (DCM) converters such as boost and flyback converters are well suited for low power applicati...
متن کاملGeneralized Average-current-mode Control of Single-phase Ac-dc Boost Converters with Power Factor Correction
The dissertation presents a generalized average-current-mode control technique (GACMC), which is an extension of the average-current-mode control (ACMC) for single-phase ac-dc boost converters with power factor correction (PFC). Traditional ACMC is generalized in a sense that it offers improved performance in the form of significant reduction of the current control loop bandwidth requirement fo...
متن کاملA Novel Method for Modeling and Simulation of Asymmetrical Impedance-source Converters
Z-Source converter or impedance-source converter is a kind of power converters, which has the responsibility to convert the direct current to alternative current. This converter with respect to its circuit diagram acts as a buck-boost converter except it doesn’t use from DC-DC converter bridge. Γ-source inverters are one of the conventional converters based on impedance-sources; which have been...
متن کاملA Topology Survey of Single-Stage Power Factor Corrector with a Boost Type Input-Current-Shaper - Applied Power Electronics Conference and Exposition, 2000. APEC 2000. Fifteenth Annual IEEE
A topological review of the single stage power factor correctted (PFC) rectifiers is presented in this paper. Most of reported single-stage PFC rectifiers cascade a boosttype converter with a forward or a flyback dc-dc converter so that input current shaping, isolation, and fast output voltage regulation are performed in one single stage. The cost and performance of a single-stage PFC converter...
متن کاملA Simple Fast Voltage Controller for Single-Phase PFC Converters
In this work a simple and robust voltage controller is proposed to improve voltage dynamics in the Power Factor Corrected (PFC) converters. The proposed controller eliminates twice the line frequency ripples from the voltage feedback path allowing large bandwidth design of voltage loop controller. As the voltage ripple is cancelled without any filtering, the controller action can be exercised a...
