Maximum power point tracking (MPPT) systems are being developed to produce switching pulses with proper duty ratios for power switches to exert photovoltaic (PV) panels under maximum instantaneous generated power

usually through a traditional DC-DC boost converter. The fundamental issue

particularly for micro-grid and small-scale green DC or AC energy applications

is that the voltage supplied by the MPPT boost converter is insufficient. In order to increase resulting MPP voltage

this research proposes a new high-voltage gain DC-DC boost converter for a cascade connection with an MPPT boost converter. Input side of the proposed converter employs a switched-inductor cell to reduce input current source ripples which is a critical problem in PV systems for high-reliability applications. Additionally

a switched-capacitor cell is used at the converter's output side to boost voltage gain and reduce voltage stress across converter's power switches

which is a crucial factor for longer life of PV panel and proposed converter components

particularly semiconductor devices. Performance of the converter is assessed while taking into account variations in irradiation and temperature brought on by changing weather conditions. A prototype converter at a laboratory scale is utilized and examined. Outcomes of hardware tests support the findings of theoretical and simulation studies.
