Single-Stage Power-Factor-Correction Circuit with Flyback Converter to Drive ...Asoka Technologies
White light emitting diode (LED) with high brightness has attracted a lot of attention from both
industry and academia for its high efficiency, ease to drive, environmental friendliness, and long
lifespan. They become possible applications to replace the incandescent bulbs and fluorescent
lamps in residential, industrial and commercial lighting. The realization of this new lighting
source requires both tight LED voltage regulation and high power factor as well. This paper
proposed a single-stage flyback converter for the LED lighting applications and input power
factor correction. A type-II compensator has been inserted in the voltage loop providing
sufficient bandwidth and stable phase margin. The flyback converter is controlled with voltage
mode pulse width modulation (PWM) and run in discontinuous conduction mode (DCM) so that
the inductor current follows the rectified input voltage, resulting in high power factor. A
prototype topology of closed-loop, single stage flyback converter for LED driver circuit designed
for an 18W LED lighting source is constructed and tested to verify the theoretical predictions.
The measured performance of the LED lighting fixture can achieve a high power factor greater
than 0.998 and a low total harmonic distortion less than 5.0%. Experimental results show the
functionality of the overall system and prove it to be an effective solution for the new lighting
applications.
Required Test Reports & Cerificates for LED LuminairesMichael Santiago
I had the great privilege to promote Advanced Lighting Company (ALC) to Royal Commission for Jubail & Yanbu (RCJY) through a technical presentation called "Third Party Test Reports & Certificates for Indoor & Outdoor LED Luminaires".
I was able to give an overview about LM-79-08, LM-80-08, ISTMT, TM-21-11, LM-82-12 and IEC 62461 among a few. I also discussed about UL Listing, LED Chip Datasheet and LED Driver Datasheet as required by the end-user.
This positioned ALC and its products as a qualified vendor and supplier of high quality LED Luminaires in the Eastern Region of Saudi Arabia. This gave a positive impression to ALC as a local Saudi manufacturing company but have a good business reputation in the market.
Since then ALC has been considered vendor listed in several ARAMCO, RCJY and SABIC projects, and more.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
