摘要： An inverter system for delivering energy from a source of direct current (dc) to an alternating current (ac) utility is provided. The inverter system comprises a dc/dc converter coupled to the source of dc for synthesizing a time-varying current from the dc, an output inductor coupled to the dc/dc converter, and an inverter coupled to the output inductor for supplying the time-varying current to the ac utility in phase with a voltage of the ac utility.

摘要： The present invention provides an improved control methodology for maximum power point tracking (MPPT), anti-islanding, and output current regulation for distributed generation sources connected to a utility grid. The control includes enhancements for MPPT and regulating the inverter output-current that is sourced into the utility grid. In addition, the functions associated with MPPT, anti-islanding detection and output current regulation are integrated together; the MPPT algorithm operates in conjunction with the anti-islanding detection, and the output current regulation operates in conjunction with the MPPT algorithm.
