Power Factor Correction in Digital World
نویسنده
چکیده
There are various reasons why power factor correction circuit is used in various power supplies in large systems. The PFC (Power Factor Correction) at input stage becomes real necessary when the input power goes above 1kW typically. Recent advances in PFC include interleaving of two out-of-phase circuits to gain many system level advantages. Enough has been discussed about the advantages of interleaved PFC; in this article we will focus on a comparison of the analog approach to the digital approach.

Optimal fast digital error correction method of pipelined analog to digital converter with DLMS algorithm
In this paper, convergence rate of digital error correction algorithm in correction of capacitor mismatch error and finite and nonlinear gain of Op-Amp has increased significantly by the use of DLMS, an evolutionary search algorithm. To this end, a 16-bit pipelined analog to digital converter was modeled. The obtained digital model is a FIR filter with 16 adjustable weights. To adjust weights o...
متن کاملLocal Field Correction Effect on Dicluster Stopping Power in a Strongly Coupled Two-Dimensional Electron Gas System
We calculate the stopping power for heavy-ion diclusters moving in a strongly coupled two-dimensional electron gas system by using the local field corrected dielectric function at finite temperature. We obtain a parameterized local field correction factor based on a relation between the thermal compressibility and exchange-correlation energy in two-dimension. The interpolated parameter is deriv...
متن کاملAn Isolated Off-Line High Power Factor Electrolytic Capacitor-Less LED Driver with Pulsating Output Current
One of the most efficient lighting technology is based on light-emitting diodes (LEDs). Common LED drivers with AC-input (50-60Hz) usually require a bulk electrolytic capacitor to decrease low-frequency ripple in the output. However, the critical element that limits the lifespan of the LED driver is the electrolytic capacitor. An isolated off-line LED driver is proposed in this paper, in which ...
متن کاملModified Bi-directional AC/DC Power Converter with Power Factor Correction
Most existing power converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...

In this paper CCM/CVM operation and modeling of the improved Sheppard-Taylor based power factor correction (PFC) rectifier is presented and a predictive control strategy is introduced for this rectifier. Compared with conventional boost or buck–boost PFC’s, this topology allows a better current tracking at the AC side, with a relatively reduced voltage at the DC side. Consequently, ...
