Abstract:
1. A system for controlling operation of power inverter switches, comprising: control circuitry configured to generate signals for timing of state changes of the switches; a data conductor coupled to the control circuitry for conveying the signals from the control circuitry, wherein the data conductor comprises at least two optical fibers, wherein a first optical fiber is dedicated to transmitting signals from the control circuitry to the power layer circuitry, and a second optical fiber is dedicated to transmitting signals from the power layer circuitry to the control circuitry; power layer circuitry coupled to the data conductor and configured to receive the signals and to recompute the timing for the state changes based upon the received signals; and a plurality of solid state switches coupled to the power layer circuitry and configured to change state to convert input power to controlled output power based upon the recomputed timing.
