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.

hello i am a computer engineer,i have masters in computer engineering,i have experience for more than 8 years in Micrcocontroller and electronics,i can make to u the design for the required UPS ,i have 3 options to offer to u the suggested solution and i am happy to discuss them with u ,2 of the solutions are plug and play from existing components,and one is a special design that i have made before,i can start immediately and deliver to u the solution within less than 48 hours

Hi, My name is Junaid. I am an experienced electrical engineer with specialities in PCBs and power circuit design. I can provide an efficient solution for 24V to 12V DC DC converter with continuous load current upto 10A. There are many ready made modules available as well. If you want I can design you a cheaper and simpler PCB using those modules. This way certification would be much easier. For battery charging we have to put on board over voltage and over charge protected circuit to safely charge battery. If interested I can provide more details in inbox. Thank you.

Dear Client. I have just read your job description and your project is really interesting to me. I have many experiences working for 7+ years with Circuit design, PCB design, manufacturing functional prototyping with firmware programming and testing especially. Here are some of the experiences that I built ago. - Schematic and PCB design and Layout using Altium Designer, Eagle, KiCAD, OrCAD. - high-speed, flexible, Multi-Layer PCB design. - DDR, motor control, power converter, UART, SPI, I2C, RF, BLE design - ARM, DSP, MCUs, Arduino, Raspberry pi experiences. I am sure I can complete it on time with high quality. If you hire me, I can start to work for your job immediately. I'll do my best for you. Thank you for your time. Best regards.

Hello, thank you for your job posting. 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.

hello sir, how are you. I read your proposal and i am interested in this project. Sir I designed some projects on solar (DC to DC converter).

Hi, I am an electronic engineer in product design domain with years of experience (though not on freelancer). Going through your job details, I felt the most important thing would be product reliability and meeting the certification standards. While your requirement is not electronically challenging, I think understanding and meeting the product quality is. Looking at the spec I could say the product can be provided under €600 at production stage. Do send me a message if you want to discuss the specifics of the project, or to discuss the best option for you to meet the requirements. I'll be happy to respond to any query you may have. Cheers,
