Hi, I am an experienced electronic/electrical designer and have designed rectifiers, inverters and DC-DC converters. I can design the power supply for you; including schematic, PCB layout and BOM within one week. I am able to get started promptly. Sincerely, Michael Cooke, PhD, EIT IHS Consultations

Dear Client, Before I placed my bid here, I already evaluated and analyzed my solutions. I got two solutions; first is with a transformer and the second one has no transformer. Since you are OK with no isolation, I focus on the no transformer design. Particularly my solution is using an AC-DC buck converter (switch mode) that can handle universal voltage range 85-265Vac. The operation is can be extended down to 80Vac without any problem as the current limit of the controller is not yet reach with the 3.3V, 500mA. I already performed high level design wherein I able to select the parts and get the advanced BOM cost. So far my BOM cost is less than 5$ for 100pcs costing. My solution is compact but can you please share to me to how much space you can allocated with this design? Please give me idea on the length, wide and height. By the way, are after only with a complete circuit schematic? I can further offer you PCB layout if you wanted to do so. I look forward in working with you. Hoping to hear from you soon.

Hi, Please share your complete project requirements(like board space available for converter). About us: We have 10 years of experience in Product development. Micro-controllers we can work on PIC, STM32, PSOC and AVR and also we have all the development kit and instruments available with us. For PCB design we use KICAD v4. And for GUI C# / LABVIEW will be used. Thanks and Regards, Santosh

Hello! We are extremely interested in this project and would love to work on this project, please reply back to discuss further. Looking forward to hear from you soon. Thanks!

Hello. I can do it. Can you give me more details? All you need its schematic, BOM, and PCB gerbers?

Hi sir I am expert in electronics,so please message me to discuss more about that rectifying circuit you need to design Regards

Hi! I have designed several switched mode power electronics converters that have very small footprints. You are probably looking for the smallest possible footprint for this power converter. I am the lead engineer of a team that has designed a 1000W switched mode power inverter which measures less than 5 inches a side! A few of our products make use of AC-DC converters that are as small as 10mmx20mm. Your power requirements are very low and the design will fit in a PCB measuring less than 1 inch a side. Since isolation is not needed, the design will also be cost effective. The project will be completed in two phases. Phase-1: Schematic capturing and SPICE simulation. (5 days) Phase-2: PCB design and Gerber file generation. (5 days) After submission of the project, I can also develop a few samples of the device at a nominal additional price of $250 for 3 units. Sample development time will be around 3 weeks. I will provide all relevant files along with a detailed datasheet and documentation of the device at the time of project submission.

I'm a an engineering student with advanced experience at Circuits analysis and design, this is my first freelancing job and I'd really be grateful if i was given the chance to carry out this job for you, I'll first simulate the circuit using Proteus and Then design the PCB Layout to take as Little space as it possibly could, then I'm going to print the layout and fit the components to the PCB, then I'll run a real time test to see if it's functioning as ordered, then I'll be shipping it at the address you provide me with, which will be the trickiest part considering I live in Egypt, and I'd be pleased to hear from you to discuss further details.

I believe that I'm the best candidate for this project. I have done graduation in Electronics engineering and during my graduation period I have designed power supplies, UPS and many more projects in which power supply is needed. If you give me this project I will never let you down

A proposal has not yet been provided

Bid Summary Design Cost : 200, Component Price :200 Relevant Experience Hardware Board design:

I have ready piece which I already worked before. Connect with me for more details

A proposal has not yet been provided

What size should a printed circuit board be? Where this converter will be used?

I have experience in power electronic with high efficient ratio (flyback configuration). I can design the PCB using "altium design" with all needed simulation, in comliance with EMC regulation.
