Title:
DIFFERENTIAL POWER PROCESSING APPARATUS FOR PHOTOVOLTAIC POWER GENERATION
Document Type and Number:
WIPO Patent Application WO/2024/048850
Kind Code:
A1
Abstract:
The present invention relates to a differential power processing apparatus for photovoltaic power generation. The differential power processing apparatus for photovoltaic power generation according to the present invention comprises: a first terminal connected to a negative output terminal of an external first photovoltaic module; a second terminal connected to a positive output terminal of the first photovoltaic module; a third terminal connected to a negative output terminal of an external second photovoltaic module; a fourth terminal connected to a positive output terminal of the second photovoltaic module; a first switch positioned between the first terminal and the fourth terminal so as to mediate the electrical connection between the first photovoltaic module and the second photovoltaic module; a second switch connected between the second terminal and the third terminal; a third switch having one end connected to the third terminal and the other end connected to the second switch; and an inductor having one end connected to a first node located between the second switch and the third switch, and the other end connected to a second node located between the first terminal and the first switch.
