DIFFERENTIAL GEOMETRY BASED DC/AC INVERTERS

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.
