electronics

Hi, I am a post graduate power electronics engineer and having very good industrial experience of 8+ years in R&D and project development. I am excellent welding power supplies design, Plasma ARC power supplies, high frequency transformers design, solar grid tie transformers, electrical vehicles design, circuits design, multi-channel LED Drivers, Regulated power supplies design with universal input to DC output, Audio amplifier, drives design, Filters design for harmonic analysis and Power factor correction, SMPS, LED drivers, DC-DC, AC-DC converters design, PFC interleaved boost converter, Battery management system, Battery chargers, UPS design, sine wave Inverters, solar grid tie inverters, Solar battery chargers and street light systems design from few watts to KW range using Buck, Boost, and Buck –boost, Interleaved boost/buck, Fly back Push Pull and H-bridge inverters. I have very good experience to design high voltage power supplies up to 50KV for capacitor charging power supplies using soft switching topologies. I have work experience to design from few watts to KW range meeting all compliances like EMI/EMC and safety standards UL etc.

I have done my MS in Electronics Engineering and I also have good experience of Power electronics or electronic switches. I have also implemented different complex circuits in hardware.

hi sir good morning i'm an expert engineer i can work with your power control system . I'm profesional and cheap my work is of HQ .So you Will like it so much.

This is a mutual agreeg contact which you can faith on quality and ontime delivery of work. Relevant Skills and Experience Dedicated electronic and electrical engg team where fulfilling your need is not a big deal.

I had experience in all switching topologies.. I can do your project.

Hi there, I would be happy to work on your project immediately. i'm familiar with electronic and power electronic switch .my gradation project was (high power inverter) that made me familiar with many types of mosfet and bjt i have also experience in PWM and how create it using psoc and AVR microcontroller however i am new to freelancer and looking to get a few clients that i can build upon .if will do it for $9/H What you’ll receive: Short list that paints a clear picture of what you will deliver (and by when) should the client hire you to do the job. Send me a quick message and we can figure out if we are a good fit to work together! ayman

Dear Sir: Thank you very much for your polite offer; Let introduce briefly myself: I've been working from 23 to 56 years old on the electronics R + D field: first few years in Audio and later Power & Industrial laboratory duties -circuit design, calculus, PCB generation, prototyping, testing & final startup- (“power” is here until 140 A / 20 kHz for low-voltage transistors and 21 kVA for line voltages -thyristors-; however, the small converter units has been always the more frequent designs). Text and translation fields were something which -for any or other reason- always finished devoted to me. About my passion for programming, begun with microinformatics in Spain (year 78 -when I had 18 years old-) and I should declare it has been for me more than useful in the actual electronic control field, although I'm just specialized in C++-type languages, today widely used in microcontroller systems for power electronics. I’ve been also dedicated to private education in the areas of electronics and computer science Now, retired for health reasons, I take advantage of my experience as a freelancer. You can have full confidence that, if we could agree, your project will be studied with the utmost detail and carried out with earnest professionalism. Best Wishes Carlos de los Rios

I have design several dcdc converters and look forward to hearing further details from you. Kind regards, Hugo

I have experience with circuit design (digital electronics, analog electronics, power supply, RF...), PCB design as well as hardware prototype testing and verification. I am also a full-time hardware engineer, spending most of my time enjoying power supply, system and PCB design and exploring various PCB (including rigid and flex) and power supply technologies. I have already designed great number of different switching power supplies. They were all designed to provide clean voltage rails with minimum amount of voltage ripple, interference and electomagnetic interference (I have experience with EMC also). If you are interested, I can send you pictures of some modules I have designed. During the design and development of the power supply, I would keep you up-to-date with the current status of the project. This includes schematic files, 2D and 3D drawings of the module etc. If you prefer, I can also arrange sourcing of components, PCB fabrication and prototype assembly and verification. So you can get fully working prototype that is 100% tested and functional. Please feel free to contact me so we can discuss project details.

I m 18+ years in PCB Design-Developments & analysis of Electronic circuits , Circuit testing, Quality Check, Fault finding and resolving in circuit and PCB, Optimizing circuits, proper Selection & Analyzing components for various applications as per parameters, Performance test of products, Worked on various Sensors, Voltage regulators, Motors, Micro-controller, Switching circuit, Motor drivers, Wireless modules, Communication protocols, etc. I will always be to meet your requirements.
