Abstract:
In this paper, the control design and the performance evaluation of a novel high step-up converter with an hourglass-shaped impedance network (HIN) are performed when used as an interface between a photovoltaic (PV) source and a load in a PV system. For optimum energy extraction from the PV source, the PV voltage controller design and optimization to track the maximum power point of the PV system is addressed. The converter offers the possibility of an optimum regulation of the PV voltage with voltage mode control using a simple Type-III compensation network resulting in a low overshoot, a relatively short settling time, and negligible energy loss after a change of input reference due to the maximum power point tracking (MPPT) or to irradiance change. To evaluate the performance of the HIN converter when used in a PV system, PSIM(C)software is used to perform numerical simulations using the switched model under different conditions.
