A '''variable-frequency transformer''' ('''VFT''') is used to transmit [[electric power|electricity]] between two ([[wikt:asynchronous|asynchronous]] or synchronous) [[alternating current]] [[frequency]] domains. The VFT is a relatively recent development, first deployed in 2004. Most asynchronous grid inter-ties use [[high-voltage direct current]] converters, while synchronous grid inter-ties are connected by lines and "ordinary" transformers, but without the ability to control power flow between the systems.
