A voltage regulator is a circuit that creates and maintains a fixed output voltage, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other electrical components. While voltage regulators are most commonly used for DC/DC power conversion, some can perform AC/AC or AC/DC power conversion as well. This article will focus on DC/DC voltage regulators.

Average current control of DC-DC Cuk Converters as Power Factor CorrectorIJERA Editor
The era of electronic devices in all loads due to the manufacturing technologies replaced many conventional electrical or mechanical loads including lighting loads where Light Emitting Diodes (LEDs) is becoming an emerging technique with many advantages. High frequency switching dc-dc converter is a new technology to control the load and the supply side simultaneously. Due to additional harmonics generated by these switching converters power factor correction has become a necessity in utility side. This paper focuses on the power factor correction of the supply side when employing an ideal LED load with dc-dc Cuk converter. This paper also illustrates the controlling of the power factor correction employing high switching frequency dc-dc converters. The control loops employed are discussed and the strategy for designing the compensator is also explained. The simulated results have been shown to ascertain the accepted performance of the power factor correction converter.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. The Electronic power supply integrated with the
switching regulator for converting the electrical
power efficiently from one form to another form
with desired characteristics is called switched
mode power supply.
3. It works on the principle of
switching regulation
4.
5. 1.INPUT RECTIFIER STAGE
2.INVERTER STAGE
It is used to convert an AC input to DC.(An SMPS with
DC input does not require this stage)
This rectifier produces unregulated DC which is then
passed through the filter circuit.
The inverter stage converts the DC , whether
directly from the input or from the rectifier
stage described in the block diagram,to AC by
running it through a power oscillator , whose
output transformer is very small with few
windings at a frequency of tens or hundreds of
kilohertz.
6. 4.OUTPUT RECTIFIER
If the output required is to be isolated from input ,
inverted AC is used to draw the primary windings of
a high frequency transformer.
This converts the voltage up or down to the required
output level on its secondary windings.
If the DC output is required , the AC output from
the transformer is rectified.
8. Many household electrical devices require a supply of voltage which is
both constant and well regulated ,but the voltage which comes from
power outlets are noisy AC voltages.
The power from such outlet needs to be managed by electronic circuits
which are generally referred to as power supplies, even though the power
comes from the outlets.
Basically , the AC supply from the outlet has a sinusoidal wave shape
and it is rectified in order to produce a DC voltage.
The noisy high voltage needs to be converted to a regulated low voltage
so that it can be used by low voltage electronic devices such as TV , DVD ,
Mobile,etc..
