I’m trying to get a better global understand of how the whole systems works. One thing that get me confused is what is the the voltage inverter? I’ve looked at the schematic at the end of the user manual for the sapog firmware and the FET are connected to V_bat but at the beginning of the document it written as inverter volatgae supply.
The document mentions as well the inverter being turn off in freewheeling, what does that means exactly?
Lastly in the regenerative breaking section they talk about
‘Typically, the controller’s hardware is equipped with some protection circuits that activate and dissipate the excessive energy when Vinv increases a certain threshold;’ what does that look like normally?
Really appreciate the help!
