How about this one? Is it what you are looking for? If not, can you describe more what you are looking for?
the first thing we should confirm is that the spikes are real and not noise coupling through the oscilloscope. Can you confirm this to be the case?
Secondly, are you using any sort of Isolation?
This design shows one way to add isolation https…
Just as a note, this is a Isolated sigma delta:
We also have some reference designs that show the analog sensing aspect with Opamp to the Controller internal ADC
It is possible to run the motor in open-loop using V/F or scalar control without any feedback signals - however, it is advisable to have at least 2 phase currents and DC link voltage feedback for protection. Closed loop control requires 2 phase…
the TIDA-00909 is based on the LMG5200 80V GaN Half Bridge Power Stage, which includes GaN FET driver and the GaN power FET in a half-bridge configuration.
Seems you are planning to use IGBTs power switches rather than GaN FETs. For IGBTs…
