Abstract:This paper focus on the small-signal modeling of the Z-source inverter (ZSI) photovoltaic generation system and
its main circuit design.The small-signal modeling of ZSI photovoltaic generation system is set up,and the transfer functions
of the input voltage-to-shoot-through duty cycle and capacitor voltage-to-control are analyzed.The sample average period
plays an important role in photovoltaic generation maximum power point tracking (MPPT) control,while it is influenced by
main circuit parameters including input capacitor,Z-source network capacitors and inductors.Thus,the quantitative
analysis in those parameters is the design guideline for the main circuit and sample average period.The experiment carried
on prototype
