Residential photovoltaic power conditioning system with module integrated DC-DC converters

This paper presents a residential photovoltaic (PV) power conditioning system, in which the PV power is controlled by the module integrated dc-dc converters and transferred to a power conditioning system. For managing the power, a pattern of daily operation considering the load characteristic of the homeowner, the generation characteristic of the PV power, and the power-levelling demand of the utility is prescribed. As for the control of the system efficiency, a novel module integrated dc-dc converter with low ripples of input current is presented. Basic relations for dc-dc converter are presented
