Abstract
A method of deriving synchronous switch currents for a three-phase Vienna-type active rectifier that includes the step of generating gate driver signals for each phase of the rectifier by pulse width modulation, wherein the gate driver signals include a top gate driver signal, a clamp gate driver signal and a bottom gate driver signal, and the step of deriving synchronous switch current signals from the gate driver signal, wherein the synchronous switch current signals include a top gate switch current signal, a clamp gate switch current signal and a bottom gate switch current signal.
