The goal of this project is to find a talented individual to design a BMS and provide a functional unit, as well as a BOM, and schematics. The device is a battery powered heating coil The specifications: • The load circuit has a low impedance, of about 0.8 to 1.3 Ω, it is a small nichrome heating coil • Open circuit voltage output around 12 V/ The voltage output may not be constant due to the low resistance, and will rather have a wide range once connected to a load • Higher than normal power is needed between 10-30W • The battery would provide high currents to reach the required power rating, usually 1- 6A to heat the coil • Rechargeable battery has to be able to withstand low resistance

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.

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.
