Abstract
A photovoltaic converter string is provided, to control, one of switching transistors in a buck/boost circuit of the photovoltaic converter to be conducted, wherein the switching transistors are connected in parallel to a bypass diode; and control the other switching transistors in the buck/boost circuit to be cut off. Therefore, an output voltage of the photovoltaic converter is applied to both ends of the non-conducted switching transistor in the switching transistors connected in parallel to the bypass diode, and after the output voltage of the photovoltaic converter reaches a breakdown voltage of the non-conducted switching transistor, an avalanche breakdown occurs on the non-conducted switching transistor, and a voltage of both ends of the bypass diode connected to a positive output end and a negative output end of the photovoltaic converter is clamped to be less than or equal to the breakdown voltage of the switching transistor.
