Title:
PHOTOVOLTAIC CONVERTER AND PHOTOVOLTAIC POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/001817
Kind Code:
A1
Abstract:
Provided in the present application are a photovoltaic converter and a photovoltaic power generation system. The photovoltaic converter is used for electrically connecting to a first photovoltaic module and a second photovoltaic module, wherein the first photovoltaic module comprises a first positive output end and a first negative output end, and the second photovoltaic module comprises a second positive output end and a second negative output end. The photovoltaic converter comprises a current transformer and a power conversion circuit, wherein the current transformer comprises a magnetic structure, a first positive primary winding, a second positive primary winding, a negative primary winding and a first secondary winding. The three primary windings all run through the magnetic structure and are arranged at intervals. One end portion of one of the two positive primary windings and one end portion of the other positive primary winding are respectively electrically connected to the first positive output end and the second positive output end, and the other end portions of the two positive primary windings are electrically connected to the power conversion circuit. One end portion of the negative primary winding is electrically connected to the two negative output ends, and the other end portion thereof is electrically connected to the power conversion circuit. The first secondary winding is wound on the magnetic structure. A small area of a board is occupied.
