原始语种摘要: In this study, a new multi-input high step-up inverter, based on isolated soft-switching DC–DC converter blocks is proposed. Each of these blocks can provide zero-voltage and zero-current switching for its semiconductors, which improve power efficiency. The interesting feature of this DC–DC converter is using bidirectional switches to generate both positive and negative output voltage levels in each DC–DC block with an appropriate control scheme. Each DC–DC converter operates by simple pulse width modulation control through fixed frequency and has two degrees of freedom, which provide the capability of output voltage regulation or maximum power point tracking. The proposed inverter consists of the cascaded connection of these DC–DC converters at their output terminal. This inverter can...
