Looking for a qualified electrician/electrical engineer to provide math formulas for an online solar energy system quote estimation page. The formulas need to be understandable to a team of programmers to use for a website. Shortly said, the idea is that the user will input the electrical devices they use on a daily basis, and the output will be the following: - Estimated amount of 100w solar panels needed - Estimated amount of 12v batteries needed - Estimated amount of inverters needed - Estimated amount of solar charge controllers needed Can provide more info and details in private messages to qualified candidates.

Development of a power supply for our modular controller system. Design will conform to our design standards and package requirements. High level design specifications: Input Voltage: AC(single or three phase)/DC, Min voltage 30VDC to 480VAC(678.72VDC) Outputs: Vout 1 24v 20 Amps, <80mv Peak-Peak ripple Vout 2 12v 20 Amps, <40mv Peak-Peak ripple Vout 3 5v 20 Amps, <40mv Peak-Peak ripple Current/Voltage monitoring on Input/Output voltages and Output voltage trimming through Ethernet control interface. Xilinx Artix FPGA (we can assist in the FPGA programming if needed, we have a default FPGA Circuit already designed ) with Ethernet and JTAG interface. Designs done in Altium Designer software with our component library (we have extra seats available if you do not have access to the software, if you are unfamiliar with the software you will need to familiarize yourself outside of the scope of the project). Please respond with a general outline of your proposed power supply design (block diagram is a bonus), why you are a good fit for this project, experience level with altium designer, projected timeline with milestones and cost. The individual awarded this job will have first access to our other contracts as they become available. Thank you.

I am looking for a rock star electrical engineer who is familiar with the STM32F4 MCU family to review the Altium schematics files for our product. Your own designs must always work as expected the first time, and your review must ensure the same for our product. The schematics include 10-15 modules with around 20 distinct ICs and many discrete components. I would expect a skilled engineer could do a thorough review in 8-16 hours. I'm looking for someone who can do a more thorough review within 8 hours. I expect the review to be complete within 48 hours after we agree to terms on the job. I'm not interested in working with a project manager or a team. I would need a signed NDA before I can send the review materials.

My project is to create synchronous rectifier for automotive alternator. I have already finished with the hardware (picture attached), now I need help with the software part. Basically it is three-phase bridge, created with low resistance MOSFET transistors, which need to be activated/deactivated at the precise time in order to turn input three-phase AC voltage into output one-phase DC voltage (12V). The hardware will be controlled with Texas Instruments F28069 controlSTICK microcontroller (this is a must), so I need somebody with experience in programming Texas Microcontrollers. For more details, please do not hesitate to contact me.
