A Modular Single-Phase Power-Factor-Correction Scheme With a Harmonic Filtering Function



INTRODUCTION

THE recent developments in power electronics technology
enable us to introduce power converters into
telecommunication applications to drive various loads in
single-phase power distribution systems. The expanding use
of electric loads controlled by power electronics has made
power converters an important and unquestionable part of the
modern society. Power supply systems i ....etc

Application Note 42047 Power Factor Correction (PFC) Basics


What is Power Factor?
Power factor (pf) is defined as the ratio of the real power (P)
to apparent power (S), or the cosine (for pure sine wave for
both current and voltage) that represents the phase angle
between the current and voltage waveforms (see Figure 1).
The power factor can vary between 0 and 1, and can be either
inductive (lagging, pointing up) or capacitive (leading, pointing
down). In order to reduce an ....etc

Abstract.
A novel Zero Voltage Transition (ZVT) technique based closed loop control of Boost Power Factor Correction (PFC) converter with Electro Magnetic Interference (EMI) Filter is presented in this paper. It operates at a xed frequency while achieving zero voltage turn-on of the main switch and zero current turn- off of the boost diode. This is accomplished by employing resonant operation only during switch transitions. During the rest of the cycle, the resonant network is essentially removed from the circuit and converter operation is id ....etc

Seminar Report On SWITCH MODE POWER SUPPLY
ABSTRACT
The report is an overview of Switch Mode Power Supply abbreviated as SMPS. The purpose of report is to provide a general understanding of SMPS and its applications. There is a brief discussion of historical development of SMPS, followed by the common topologies of the same. The principle of operation is described which is almost same for all the topologies. Then the steady state analysis is discussed to have an insight of the operation under ideal and real conditions. The ....etc

Abstract We consider the problem of relay-assisted transmission for cellular networks. In the considered system, a source node together with relay nodes are selected in a proportionally fair (PF) manner to transmit to the base station (BS), which uses the maximal ratio combining (MRC) to combine the signals received from the source node in the first half slot and the relay nodes in the second half slot for successful reception. The proposed algorithm incorporates the PF criterion and cooperative diversity, and is called proportionally fair c ....etc
