This dissertation presents a module-integrated isolated solar micro-inverter. The studied grid-tied micro-inverters can individually extract the maximum solar power from each photovoltaic (PV) panel and transfer to the AC utility system. A harmonic suppression technique is used to reduce the DC-bus capacitance. Electrolytic capacitors are not needed in the studied solar micro-inverter. High conversion efficiency, high MPPT accuracy and long lifespan can be achieved. The operation principles and design considerations of the studied PV inverter are analyzed and discussed. A laboratory prototype is implemented and tested to verify its feasibility.
