Hi, I am a post graduate power electronics engineer and having very good experience in product design and development. I am excellent in SMPS, LED drivers, power supplies design, solar Inverters, solar battery chargers and street lights using MPPT technology from few watts to KW range using Buck, Boost, and Buck -boost, Push Pull and H-bridge inverters. I have waste experience in LED drivers design using universal input range meeting all EMC, UL and environmental standards. I designed LED drivers with active PFC to meet high Power factor through the voltage range. I understand your requirement and ready to work for you. Please contact me for further discussion.

Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you want a EL driver board to be designed. Basically, my solution uses two main blocks: a Power Supply and an EL Driver circuit. The Power Supply circuit block could incorporate in itself a number of sub-circuits depending on the project particular operational requirements. Now, as far as the soundproof requirement is concerned, I would suggest to use sound absorbing foam. And the rest - assembly, frequency attenuation, size etc., will depend on the enclosure in which the board is to be fitted. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Block diagram (based on project requirements) 2. Components library creation 3. Schematic drawing 4. Review of schematic drawing 5. Layout design 5.1 Components placement and arrangement 5.2 Components routing 4.3 Review of layout design 6. Design rule check 7. Verification and validation 8. Review of layout design 9. Production files (GERBER, NC DRILL, STEP, BOM, ASM, PICK & PLACE) Your project will be carried out on Altium Designer. Don't hesitate to contact me with questions regarding any details around your project. I am looking forward to hearing from you soon. Thank you for your time. Kind Regards Martin Botsov

Hi, I am a Recent Graduate, completed Msc in Electrical and Electronic Engineering from Bangladesh University of Engineering and Technology(BUET). I have been working as a professional Academic Writer since 2013. I'm a conscientious worker with a focus on quality and client satisfaction. I have a proven track record of writing excellent quality papers. I have excellent academic writing skills, will complete assignments on time, and I assure quality work. All assignments are written only upon in-depth analysis, which I am sure will meet your expectations. As an interdisciplinary scholar, I'm familiar with several citation styles (e.g. Harvard, Chicago, APA, etc.) and have experience in advising and coaching students, early career scholars, and those who find writing difficult for any number of reasons (e.g. language, blocks, fears, etc.). I'd be happy to help you develop a proposal for your Ph.D. and Master’s level work through research ideas, write according to a schedule, or polish your application to university.

A silent EL driver is possible by selecting a resonant/oscillating circuit over 40KHz and discrete components that assist with the EL transducer drive. The challenge is to select a target cost that allows a solid solution with reliable components. It would be helpful to know what is the target cost for the Bill Of Materials, and the target reliability goals. Looking forward to answer in additional questions and interact to define an optimal product that satisfies your goals. Warm regards, Rene Cardenas 214 469-7100
