This paper deals with the simulation of closed loop and open loop controlled Interleaved Boost Converter (ILBC). It is seen that, for higher power applications, more modules can be paralleled to increase the power rating and the dynamic performance. One of the challenge in designing a boost converter for high power application is how to handle the high current at the input side. In this paper a...

INTRODUCTION Race may be a significant factor that influences prostate cancer (PCa) survival, with the Asian (AsA) race being associated with better outcomes compared to African American (AA) and Non-Hispanic Whites (NHW). This study evaluates race-dependent variation in PCa-specific mortality (PCSM) associated with radiation dose-escalation exemplified by external beam radiotherapy (EBRT) with...

ranking is one of the key measures for evaluating universities.  progress of research at universities is often measured by the rate of its publications.  it is also common knowledge in the field of research that journal publications owe their success to their impact factor.  however, one of the contributing factors that affect a journal's impact factor is the accessibility and availability of i...

Electrical Engineering (ABSTRACT) The conventional power factor correction circuit has a fixed output voltage. However, in some applications, a PFC circuit with a wide output voltage range is needed. A single phase power factor correction circuit with wide output voltage range is developed in this work. After a comparison of two main power stage candidates (Buck+Boost and Sepic) in terms of eff...

─The suitability of a single-stage ac-dc buck-boost converter for low-voltage applications is investigated. Indepth discussion and analysis of the converter’s operating principle, basic relationships that govern converter steadystate operation, and details of the necessary control structures needed to comply with the grid code are provided. The validity of the proposed system is confirmed using...

Single phase power factor correction ac-dc converters are widely used in industry for ac-dc power conversion from single phase ac mains to an required output dc voltage. In case of high power application these types of converter use an ac-dc boost converter followed by dc-dc converter. These converters has the features of excellent input power factor, continuous input and output currents, and i...

Due to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harm...

This paper deals with a new Cuk Topology for Power Factor Correction (PFC). Most of the front-end PFC converters are implemented using diode bridge and this results in the lower efficiency due to significant losses with reduced power factor. This new Cuk converter is a bridgeless Cuk PFC converter with two semiconductors switches. The current flow path in converter during each interval of the s...

Introduction. With the adoption of standards such as IEC555-2, there is a need to develop electronic ballasts for fluorescent lamps which can perform line current harmonic reduction and high input power factor correction (PFC). Among various filtering techniques, the active power factor corrector with a tioost converter has, been proven to be effective [l 31. The boost-type PFC circuit is one o...
