Architecture and control method for dynamically conditioning multiple DC sources to drive an AC load

摘要

A power electronics and control architecture for powering an AC load from a multi-source power system through a single conversion stage is disclosed. A controllable DC-to-AC inverter accepts a DC output voltage range from a DC power source at a DC input, and outputs an adjustable AC at an AC output. A sensor measures an output power of the DC power source to obtain a measured output power, and a processor sets a power level at the DC input based on the measured output power. The processor sets the power level to control the output power of the DC power source, and synchronizes the adjustable AC to a common AC output of the multi-source power system.
