[electricboats] Regen under sail

Hi all, 

Very interesting discussions going on, thank you for your inputs.

I was told that AC induction motors like mine are very bad /useless for regen.

Would you agree?

Aren't AC induction motors used in EVs with "relatively good" regen?

Cheers

Mich

Cycling through 4x series-connected 12v batteries will require a high current, isolated multiplexing circuit. The loss generated by the switching components will likely be as great a loss as a buck converter from 48v to 12v. And, the electrical noise introduced onto the DC bus will need to be handled because it will be pretty extreme since overlapping during the switch won't work due to the need to be isolated (so as not to get 24v when the circuit expected 12v). I recommend multiple smaller (~50a) buck conveters because they run nicely in parallel and can give you some redundancy. I run 4x 50a 96v to 12v converters on a main 12vdc bus and 4x 15a 96v to 12v converters on 4x isolated special purpose 12vdc busses.
