The usual way to achieve what you want is to have a bidirectional PFC (also called AFE - active front end) and a H-bridge output stage instead of a passive rectifier. So the converter is able to transfer energy in both directions. No switchover is required in this case, just set a negative current setpoint to the controller.
LLC, is, we have found, the only topology that facilitates bidirectional power flow. The basic full bridge smps offers up too many problems in terms of overvoltage spikes due to transformer leakage when going "backwards".I'm not sure if bidirectional LLC is a suitable way. The bidirectional power supplies that I know, e.g. battery testers up to 180 kW are following a more conventional design concept..
Thanks, we definitely don't want to reinvent anything, just want to get the job done as cheaply and simply as possible. Are you saying that these are off-the-shelf items, that we can just buy? We haven't seen any.But anyhow, I just wanted to mentioned that "grid friendly" drives and power supplies with recuperation capability are widely used in industry and green energy applications. Don't reinvent the square wheel.
