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 high frequency transformers design, circuits design, Regulated power supplies design with universal input to DC output, 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 work experience to design from few watts to KW range meeting all compliances like EMI/EMC and safety standards UL etc.

Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for a hardware engineer capable of diagnosing and repairing an already designed and built amplifier circuit. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Research 3. Diagnosis 4. Test & measurements 5. Review and discussion of discovered problems and their solutions Important notice: If you happen to send the circuit board at my workshop, then you should be aware that all freight costs (in both directions) are covered by the employer. Important notice: The proposed delivery schedule regards only for the time of receiving the board. Transportation schedule is not included in the proposed delivery term. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for your time. Kind Regards Martin Botsov

you have to do impedance matching of your amplifier output I gave you the solution key. you can search the Internet and try it by yourself. I you still have problems then accept my bid and i can help

ı have design knd of circuit just before 4-5 mounts in analog lecture, so ı can make your work best.

hello, i can help you with your project. You need to specify what you exactly need. Just working schematic if i understood well? If you have any question, feel free to contact me on chat. I would also like to see what you done until now, before you accept offer.

Sir I would like to interest this type of projects. We have a team of dedicated engineers are there like Circuit Designer, PCB design engineer, firmware engineers. We have done many Projects in domestic clients (india). If you Assign the project to us you will best solution of the project. Thank you

Hi this is Asif from karsan technologies pvt ltd, coimbatore.... We have hardware lab in our company.... So we able to test and solve the issue.. Where are you from?? The price for the project ll be revised after the sharing the circuit diagram,,, pls initiate the chat session

I have work on amplification of signal. My experience help my to resolve your problem. You can try me for your project

I can troubleshoot problem and I can suggest how to optimise circuit with latest components from Texas instruments, silabs,nxp and other popular vendor all over the world.

i cant say anything without the circut, even if u don't puck i would like to see the circuit, what kind of AMP im assumig a class d type
