Electronic Ballast Platform - EBP
In this paper will be reported the implementation of a flexible platform to study electronic ballasts systems. The platform is a microcontrolled and FPGA-based system and was developed to generate command signals to the half bridge inverter. A specific hardware using FPGA was developed to generate the switches signals command. This hardware is responsible for the autonomous frequency (FM) and p...
متن کاملDigitally Addressable DALI Dimming Ballast
A digitally addressable digital dimming ballast has been developed. It conforms to DALI standard requiring very few parts and operates at very low power. Applications include building management or studio lighting where it is desired to control single or groups of lamps for conserving energy, performing lamp maintenance or creating prefect light quality. The design includes the digital dimming ...
متن کاملUse of Ballast Support Condition Back-Calculator for Quantification of Ballast Pressure Distribution Under Concrete Sleepers
In North America, most rail corridors are constructed using ballasted track. Monitoring the ballast support condition and improving upon current sub-structure/ballast maintenance strategies will ensure safe railroad operations. However, it is inherently difficult to evaluate the pressure distribution at the sleeperballast interface. Researchers at University of Illinois at Urbana-Champaign (UIU...
متن کاملHeesang Park, Jongil Park and Dongsoo Shin
This paper is an addendum to [4], in which the authors constructed a simply connected minimal complex surface of general type with pg = 0 and K 2 = 3. Motivated by Y. Lee and the second author’s recent construction on a surface of general type with pg = 0, K 2 = 2 and H1 = Z/2Z [3], we extend the result to the K = 3 case in this paper. That is, we construct a new non-simply connected minimal su...
متن کاملSimple Control Circuits for Electronic Ballast Design
Electronic ballasts are designed to fulfill a variety of different input and output specifications depending on their end application and performance requirements. These designs typically include non-PFC, passive PFC and active PFC input stages, and, single, dual or multi-lamp output stages. The input voltage requirements for each design can vary significantly depending on the final application...
