Abstract
A gate driver communication system includes a cored transformer including a primary coil and a secondary coil configured to receive power signals and uplink data signals from the primary coil; a primary side power signal generator coupled to the primary coil and configured to generate the power signals having a first frequency; a primary side data transmitter coupled to the primary coil and configured to generate the uplink data signals having a second frequency different from the first frequency; and a primary side controller configured to allocate the power signals and the uplink data signals to the primary coil according to a plurality of time slots, wherein the power signals are allocated to first time slots of the plurality of time slots and the uplink data signals are allocated to second times slots of the plurality of time slots.
