For variable speed wind turbines, one of two types of generators can be used: a (doubly fed ) or an FRC (fully rated converter). A DFIG generator draws from the transmission system; this can increase the vulnerability of a transmission system in the event of a failure. A DFIG configuration will require the generator to be a wound rotor; squirrel cage rotors cannot be used for such a configuration.

High-frequency inverters use lightweight ferrite core transformers operating at 20-100 kHz, making them compact and efficient for electronics. Choosing the wrong frequency can lead to device failure, poor performance, or even hazards. There are two main types of inverters: low-frequency inverters and high-frequency inverters. Think about your power needs before you choose.
