Patent ID: 8400791

Claim:
A system for controlling operation of power inverter switches, comprising: control circuitry configured to generate gate timing-related signals for timing of state changes of the switches; a data conductor coupled to the control circuitry for conveying the gate timing-related signals from the control circuitry; power layer circuitry coupled to the data conductor and configured to receive the gate timing-related signals and to recomputed the timing for the state changes based upon the received gate timing-related 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; wherein the control circuitry is configured to periodically transmit synchronization signals to the power layer circuitry and the power layer circuitry is configured to adjust a power layer clock between the synchronization signals to compensate for variability in an operating frequency of an oscillator upon which the power layer clock is based.
