- Abstract
A 1 kW photovoltaic grid-connected inverter which uses DSP28335 as the core processor is proposed. Two-stage topological structure is adopted for DC/AC conversion in the inverter. A non-isolated coupled inductor voltage doubler cell Boost converter is used in the pre-stage, it realizes high voltage gain and low loss of the circuit. The double closed-loop control strategy based on PI adjuster is explained. The design process of main circuit and control circuit is introduced in detail. The experiment shows that the prototype meets the proposed design criterion. [ABSTRACT FROM AUTHOR]
