Zusammenfassung:A series type photovoltaic array is characterized in that the photovoltaic array is formed by n photovoltaic group string power units which are connected in series, wherein n>1, and each photovoltaic group string power unit is formed by a photovoltaic group string and a photovoltaic group string high-voltage isolation power regulation module which are connected in series. Output ends of the photovoltaic group strings are connected with input ends of the photovoltaic group string high-voltage isolation power regulation modules, voltage is output through DC/DC isolation ports of the photovoltaic group string high-voltage isolation power regulation modules, and a withstand voltage of each photovoltaic group string power unit is higher than a direct current system voltage Usmax.
