OK, all of you power electronics engineers, here is a query from a friend of mine studying in the smart grid area. I will PM Ingineer and TonyWilliams. Others who might know more? As a preface, I don't really understand this stuff, so please feel free to reply with technical or dumbed down information. I will pass along verbatim. Thanks in advance.
I was looking for some information about the ability of EV chargers to withstand frequency deviations from their supply. I thought this would be a straightforward Google query, but I can't seem to turn up anything that answers what I'm looking for. The closest sources discuss the ability of smart chargers to use frequency as a signal to determine when to charge (e.g. smart grid applications). That's actually the reverse of what I want. I just want to confirm my assumption that EV chargers are relatively insensitive to frequency variations in the AC source, much like other power electronic interfaces.
