Abstract: A distributed power system including multiple DC power sources and multiple power modules. The power modules include inputs coupled respectively to the DC power sources and outputs coupled in series to form a serial string. An inverter is coupled to the serial string. The inverter converts power input from the serial string to output power. A signaling mechanism between the inverter and the power module is adapted for controlling operation of the power modules. Also, for a protection method in the distributed power system, when the inverter stops production of the output power, each of the power modules is shut down and thereby the power input to the inverter is ceased.

Abstract: A DC/AC inverter and microinverter architectures using the DC/AC inverter are disclosed. The DC/AC inverter is based on a differential geometry control scheme to balance and optimize the flying capacitor voltages across the flying capacitors used in the inverter's power circuit. Based on changing inverter and overall system conditions, including capacitor voltages, grid voltages, grid current, and DC bus voltages, desired fields are generated. These fields are used to balance capacitor voltages such that capacitor voltage values converge, over time, to an optimal solution.
