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). ....etc

A Digital DC Power Supply (programmable bench power supply unit), hardware version 3.0
Abstract:
A good, reliable and easy to use bench power supply unit is probably the most important and most used device in every electronic lab.
A proper electronically stabilized bench power supply unit is an important but also expensive device. Using a microcontroller based design we can build a power supply which has a lot of extra features, is easy to build and very affordable.
The tuxgraphics digital DC power supply ....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”
This paper presents a simplified sinusoidal uninterruptible power supply (UPS) system. The proposed scheme includes features such as high power factor, low total harmonic distortion and good dynamic response at the ac output voltage. In addition, the scheme has the desirable characteristics of high efficiency, simple circuit and low cost compared with a traditional standalone multiple stages UPS with power factor correction. The paper also presents the circuit operation, the analysis and, experimental results of the proposed U ....etc

Abstract”
A major disadvantage of applying sliding mode control to dc/dc converters is that the steady-state switching frequency is affected by line and load variations. This is undesirable as it complicates the design of the input and output filters. To reduce switching frequency deviation in the events of line and load variations, an adaptive feedforward control scheme that varies the hysteresis band according to the change of line input voltage and an adaptive feedback control scheme that varies the control parameter (i.e., sliding c ....etc

Am rema,want to know about an efficient common mode hybrid filter used in SMPS for my seminar work.


Abstract obtained from IEEE is After the study of electromagnetic interference (EMI)
mechanisms in switching mode power system (SMPS) and the soft
switch, this paper proposes a novel hybrid filter (HEF) to suppress
commend mode EMI in SMPS. The HEF consists of a passive filter
and an active filter. Matching network, which can reduce
impedance mismatching effects, is introduced in passive part. A
