摘要： A device, system, and method for global maximum power point tracking comprises monitoring an output power of a DC power source while executing a maximum power point tracking algorithm and adjusting a maximum power point tracking command signal in response to the output power being less than a reference output power. The command signal is adjusted until the output power exceeds a previous output power by a reference amount. The command signal may be a voltage command signal, a current command signal, an impedance command signal, a duty ratio command signal, or the like.

摘要： An inverter for converting an input direct current (DC) waveform from a DC source to an output alternating current (AC) waveform for delivery to an AC grid includes an input converter, an output converter, an input controller, and an output controller. The input controller is configured to control the operation of the input converter, and the output controller is configured to control the operation of the output controller. The input and output controllers are electrically isolated from each other and may be incapable of direct communications between each other. In some embodiments, the input and output controllers may communicate with each other via the input and output converters.
