We have the habit here at Oztek of using the term "active front-end" (AFE) and grid tie inverter (GTI) interchangeably. On more than one occasion discussing our grid tie inverter controller, I’ve caught myself somewhere mid-conversation inadvertently switch to using the term active front-end. It's of no concern internally, but quite frequently its cause for confusion when speaking with customers. Earlier this week I received a call from a customer that was pretty certain an AFE would not work in his GTI application. This got me thinking, "What exactly is the difference between an active front-end and a grid tie inverter?"
