“…For example, fuel cells and solar photovoltaic (PV) devices produce low voltages (lower than 50 V), which is too low to connect with the electric grid or supply residential loads. To solve this problem, a large number of DC‐DC boost converters have been proposed 1‐5 . The topologies of step‐up converters can be divided in nonisolated and isolated, 6 noncoupled‐inductor and coupled‐inductor converters, 7 which have been extensively investigated in the past few decades.…”

Summary In this study, a novel high‐step‐up converter is proposed with a new hourglass‐shaped impedance network (HIN). Due to the short lifetime of electrolytic capacitors (ECs), the proposed converter uses nonelectrolytic capacitors (NECs), which however can realize all ECs' features. Besides, the proposed converter has low capacitor voltage stresses, ensuring it could be electrolytic‐capacitors‐free. With this feature, the proposed high step‐up converter has smaller size, lighter weight, smaller parasitic resistance, and longer operation life than the conventional ones with ECs. In this paper, detailed operational principle and performance of the proposed converter are presented, to demonstrate its advanced features. Simulation and experimental studies are also carried out, which validate the feasibility and effectiveness of the proposed converter.

Summary 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©software is used to perform numerical simulations using the switched model under different conditions.
