摘要:
In order to offer a power supply circuit that can minimize the drop in efficiency by reducing losses during voltage conversion, in an improved-power factor circuit, a control circuit performs a step-up operation in which a control signal for turning on a first switching element (Tr1) and switching a second switching element (Tr2) is output, and a step-down operation in which a control signal for turning off the second switching element (Tr2) and switching the first switching element (Tr1) is output.

Disclosed is a photovoltaic device 1 including a plurality of cluster power generation sections G (G11, G12, G21, and G22). Each cluster power generation section G includes unitary power generation sections D (D1, D2) connected in series via connection points CP12. The cluster power generation sections G each have at least a predetermined one of the connection points CP12 designated as a specific connection point SP12. The specific connection points SP12 are connected together to link the cluster power generation sections G.
