  • Alternating current (AC) synchronization for load restoration
    Patent number: 9240706
    Abstract: Among other things, one or more techniques and/or systems are provided for synchronizing one or more direct current (DC) to alternating current (AC) power sources (e.g., a DC power source coupled to an inverter) for restoration of power to a load. That is, responsive to a grid fault of a grid used to supply power to a load over a common bus, the common bus is isolated from the grid and the load. One or more DC to AC power sources are synchronized through synchronization circuits (e.g., voltage, phase, and/or frequency synchronization) until a total power supply provided by respective synchronized DC to AC power sources is greater than or equal to a target power used to supply the load. Once the target power is achieved, a load circuit breaker is closed so that respective synchronized DC to AC power sources provide power to the load over the common bus.
