Dear Hiring Manager, I'm a professional electrical engineer with 4 years of experience here as a freelancer. I've a very well established freelancer profile all because of my dedication to work and excellent relationships with my clients. Coming to the project. I've hands on experience in designing DC/DC, DC/AC inverters etc. I've expertise in MATLAB, ORCAD, PROTEUS for software simulations. Regarding STM32 (honestly I don't have enough experience with STM family, I usually work with PIC/ATMEL etc, so I would like to use the same for your project (without compromising quality). The Good Qualities of mine: 1- I stay connected with my clients during the project, and provide them regular updates. 2- I'm the man of my words, I deliver the work on time. 3- I don't compromise on the quality of work (so my rate might be a little higher than other competitors). 4- I provide free support (for upto 15 days) after the completion of project so that you're 110% satisfied. That's about me, you can have a look at my profile and read the wonderful reviews my clients give. I will provide circuit design (how I designed), circuit schematic, simulation, source code. Feel free to contact me if you have any inquiries. Regards. Faraz Ahmad

Hi I looked at the specifications you mentioned for the project, and just have a question, what the input voltage you need for the converter? I understand all the specifications except this point, if the source is 3-phase what is that input voltage then? Hope we talk so you clarify to me And about the pcb design and prototype, i can do any look at my reviews. Hope i hear from you Regards

I'm expert in power electronics. I've made projects before related to the field of power electronics such as a 500-watt maximum power point tracker for the solar car project and also a 250-watt DC motor driver. I've programmed the controller in the maximum power point tracker which was an atmel microcontroller. I've made also the PCB designs for both projects so you'll be amazed with the quality of work. I guarantee the best quality and delivery on time. Price is negotiable. Check my portfolio for details.
