Abstract :
This paper presents the design and implementation of a DSP-based grid-tied solar cascode-micro-inverter. The proposed solar inverter with maximum power point tracking (MPPT) function is connected with the AC grid by a cascode-circuit configuration. Due to the studied single-stage power conversion, high conversion efficiency, high MPPT accuracy and low harmonic distortion can be achieved. A 300W laboratory prototype was implemented and tested to verify the feasibility of the proposed scheme.
