Design a Power Supply for automobile usage

Hi Sir, We offer our services at very feasible rates. Please discuss with us in details. Let me give you a brief introduction about Turktronics. At Turktronics, We are team of developers and engineers professional in designing electronic circuit solutions, pcb designs, database programming such as MySQL etc, software designs and GUI/UI development, android applications, integrating software and hardware and providing complete solutions. In this bid, we offer you our solution at very low and affordable rates based on your desired requirements. we normally follow several checks to ensure the quality of service and products. In this bid prototyping is not included, if at certain point you would like to have prototypes manufactured, we can provide you at minimal cost including courier charges (DHL/FedX etc). We, very humbly deal with our clients and provide full technical support during all phases of project execution. We are very much looking forward to hear from you in coming days. Cheers, Ahmad Lead Technical Engineer Turktronics Inc. An Internet of Things Company

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, high frequency transformers 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.

The expected BOM cost will be around 200 Rupees and bid amount includes designing the schematic, development of the PCB layout and supplying you 3 nos prototype on home brew PCB. I think to validate the design, 3 nos is more than adequate for the purpose. It will be EE16/EE20 ferrite transformer based non isolated design. I have electronic load, digital scope and testing power supply so I will do the first phase of testing before delivery. My only request is, recently I had very bad experience with an Indian regarding payment. So please dont consider offering me the job in case if you are reluctant to add the money in milestone at the time of offering the job. Yes, you dont need to release it soon after I deliver the product. I will send it to you, test it for a week and then release it. The cutoff voltages will be 9V and 70V and will deliver 12/2Amp output. Please note that when operating at input 9V area and output still draws 12V/2Amp, then input current may not be exactly 3Amp, but will be little higher than that. at this BOM price, synchronized DC-DC conversion is not possible which will add more cost to the BOM as well as to the designing fees. I have been working on such power supply since last 3-4 years so quality is ensured. Thanks for your time and I look forward to hear from you. Regards... Roy

Hello, Greetings of the day, I have gone through the description & found interesting.

Hi We can give you a design for the automotive power supply according to the specs you have mentioned along with the prototypes and other safety features built in. We are located in the southeastern part of India and once you are ready we can discuss things. Regards

dear sir, i am an electronics engineer. i have designed linear amplifier cards which included a wide range dc dc converter circuit. u have designed emi emc compliant electronic systems. i am from your home country. feel free to tell me more about the system. Dear Sir, I have designed the circuit for 9-70V input and 12V output. Per unit cost of the board will be around 800 Rs for original components and 550 for generic components. I have already designed and performed psipice simulation for the circuit for 12V/2A output. The cost of 5 no of board will be 4000 rs. My design charge of circuit in EAGLE, layout charge etc will be 6000 rs. and 1000 is the website fee. That makes it 11,000. I am from your home country and southern part it. Kindly ask for any other clarrification
