Abstract
A multiphase converter for reducing the input and output current ripples. The multiphase converter includes a system controller and power devices. Furthermore, the multiphase converter includes an active gate driver integrated circuit (IC) electrically connected to the system controller and the power devices. The active gate driver IC receives signals from the system controller and provides outputs to the power devices based, at least in part, on real-time feedback from the power devices.
Claims7
