I am currently designing a BLDC controller and keep running into a power safety issue:
I have added a smart diode reverse protection controller to my design with its transistor between the fuse and the bulk capacitance (4 x 220uF elcap bank).
This was done to protect all downstream components (and the polarized capacitors especially) from reverse polarity events. Now obviously this poses a big problem during regenerative braking since the IC (LM5050) interrupts the supply line and makes the micro think an undervoltage event occured (which it momentarily did, since the power to the motor was cut).
What is a good way to mitigate/solve this issue and how does this get solved by real electronics designers?
