You better check with the VFD manufacturer before you waste your money on a VFD. If you have a 3 phase gen set, I suggest you get a 3 phase charger.
You stated: "Would a "bad boy" full wave 3 phase rectifier work? (I'd probably need to adjust the voltage output of the generator.)" With this approach, you are looking for trouble. "Is it possible to build a voltage regulator that adjusts the voltage QUICKLY in order to get something closer to a square wave output rather than the normal sine wave?" At 12KW - 60KW, this is serious design project. Expect to spend a lot of time and money. If you have a 3 phase gen set, I suggest you get a 3 phase charger or sell the gen set to someone that needs 3 phase electricity. ________________________________ From: EV <[email protected]> on behalf of Matt Lacey via EV <[email protected]> Sent: Saturday, March 3, 2018 10:40 PM To: John Lussmyer via EV Cc: Matt Lacey Subject: Re: [EVDL] 3 phase range extender? No, a vfd can go in both directions. Same concept as using one as a motor controller. You're basically getting the vfd to run the genset in Regen. Genset goes on the output side of the vfd. The battery goes on the dc bus. No need to connect anything to the normal ac input Sent from BlueMail On 4 Mar. 2018, 13:37, at 13:37, John Lussmyer via EV <[email protected]> wrote: >On Sat Mar 03 21:29:22 PST 2018 [email protected] said: >>You could get a variable frequency drive to convert the ac to dc. >Assuming the get set output is 220vac or similar. > >Last I knew, a VFD output AC at a Variable Frequency.
