3 phase current source 15A/phase - fully digitally controlled
Budget: €30 – €250 EUR
I’m looking for someone to develop basic block diagram, bill of material, schematic and programming for proof of concept device that can produce fully contollable 3 phase (separate chanells, that can be connected togather to have common star point) curent source 0-15A, resolution of 1mA.
Current source must be capable of producing pure sine wawe of 50 or 60Hz with additional higher harmonics ( up to 10th harmonic).
MCU to be selected from STM32 range.
Design should be possible to extend to 8 currents each fully independently programable.
Values to control on each current source individualy are :
Amplitude 1mA resolution
Frequency 0.05Hz resolution, range 0-100Hz (plus higher harmonics of 50 and 60Hz)
Phase angle 0-360 with 0.1 deegree steps
