Abstract (Summary)

This thesis presents a novel power electronics sliding mode control design for photo-voltaic energy conversion systems. In order to maximize the power generation from solar panels, perturb-and-observe maximum power point tracking algorithm is applied. The purposed first and higher-order sliding mode control techniques are developed to overcome the irradiance and load fluctuation challenge, and to optimize the power conversion efficiency. Compared with the first-order method, the higher-order sliding mode approach can significantly reduce the chattering effect in the buck-boost converter. The output of the DC-DC converter is then fed into a voltage-oriented control based space-vector pulse-width-modulated inverter for three-phase AC power generation for a standalone system. Computer simulation studies have shown the effectiveness and robustness of the proposed power electronics control approach for solar energy systems.
