Power supply design with sample hardware for testing (Deliverables: design + sample-hardware)

Hello, thank you for your job posting. I read your description about--power supply I am a senior electrical engineer. I have plenty of experience in firmware development and micro-controller developments. I can write the firmware based on Arduino, Raspberry Pi, Pic, Atmega, FPGA, ARM, DSP, PLC and so on. And I can design the circuit by the Altium, Eagle, KiCAD, Allegro & OrCAD, PADs. I provide the services - Gerber files, Netlist generation, BOM generation and 3D Models of PCAD and ECAD. I am also good at AutoCAD, Solidworks. And I can simulate all circuits with Proteus, LT-spice, Matlab, Simulink, Multisim, and Labview as well. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I will also give you a detailed explanation of the process. Looking forward to hearing from you soon Thanks

What are the mechanical constraints to be taken care of? 3. What are the standards that the product would be complying to? Please try to answer these questions based on which I would be providing free of cost consultation. Please message me so that I can formulate a success plan for this project. Waiting for your reply, Regards Hari Mohan Engineering for one is a magic for others

Hi there, We can surely design the power supply with sample hardware for testing. I stumble upon your whole requirement and would request you to initiate the interview process. Here is our PCB designing process:- Create the Schematic Create and Setup a PCB Link the Schematic to the PCB Define the Board Size and Layer Stack Place Components Insert Drill Holes Route Traces Verify Circuit Board Layout Add Labels and Identifiers Generate Design Files We will be glad to hear from you! Regards, Intellisense Technology

110Vrms(AC) to 50Vrms(AC), are you looking for that?? You can use iron core transfomer for that. Ok. If you want high frequency, then we will use H bridge using IGBT. I have done similar project, 110DC to 80AC inverter, i will share you the photos. What is control? closed loop or open loop?? Please chat with me. Im from india, testing i can do in my place but components and PCB,you should pay money.

Hello, I am an Electrical Engineer with 30 years’ experience of Customized Product Development for Instrumentation and Control applications. I am based in Kolkata (India) and running a business in the name of "Zetek Systems". I have a good hardware setup and a team for fabrication and testing. In the output details you have not mentioned the frequency of the sine wave. I am assuming it as 60 Hz. Please note I have not included the shipment cost of the samples in my bid. Looking for your valued reply. Regards - Debasis Basu

Hi I am familiar with power supply options. In my past projects, i have designed power supply circuits(DC-DC, LDO), also passed testing, it works perfectly. Please contact me.

Hi, I am a electrical engineer with 12 years experience in designing. I would propose a Texas Instruments based solution if you are open to it. However FCC EC standards will require additional work we can discuss in detail. I can also provide 2 samples provided shipping is available to your address. Regards, Safi

Could you re-confirm the sine wave part? Or is a DC output suitable. For such a small enclosure, it is best to use an SMPS power supply which converts the AC input into DC then high frequency AC to step down and then again into DC. If you want to add another step into AC, then that adds another layer of complexity. Also considering the output power of 150W, a regular system will generate 20-30W of heat which is hard to dissipate in such a small enclosure. If you can share the the application, then I can help you in figuring out the most optimal design/configuration for this product. About Me- I have more than 10 years of Experience in Power Electronics systems for Industrial and Commercial use during my employment at ABB and Siemens. I am sure that I can provide the best solution for your issue.
