Abstract
An AC power sharing system for connecting an AC power source to at least two loads, the system comprising: power distribution board, the power distribution board having at least one input for receiving AC power from the AC power source; and, the power distribution board further comprising at least two relays, each relay for connecting the distribution board to a load, each switch having an OPEN/CLOSED configuration, wherein in the CLOSED configuration the relay is configured to connect the AC power source to a load to provide power from the AC power source to the load; wherein the relays comprise two IGBTs or MOSFETs arranged with their load side terminals connected in anti-series.
Claims14
An AC power distribution system for selectively connecting a first AC power source to a plurality of grid connected loads in a power sharing system comprising:
- a power distribution board having:
- i. at least one input configured for receiving AC power from a first AC power
- ii. at least two switches, each switch being configured for connecting and disconnecting the first AC power source to a separate grid connected load in parallel, where each grid connected load is connected to an electric power grid in parallel, and each switch having an OPEN/CLOSED configuration, wherein in the CLOSED configuration the switch is configured to provide power from the first AC power source to a grid connected load, with the grid connected load connected to the first AC power source in addition to the electric power grid, and wherein in the OPEN configuration the switch is configured to disconnect the first AC power source from the grid connected load such that no power from the first AC power source is provided to the grid connected load in addition to the electric power grid;
- iii. a controller configured for selectively controlling the OPEN/CLOSED configuration of the switches;
- and
- iv. sensors configured to measure total power from the first AC power source;
- V. sensors configured to measure power demand of each grid connected load;
- wherein the controller is configured to calculate power exported to the grid for different switch configurations and selectively controls switches to meet preferred power export requirements.
