Title:
POWER SUPPLY SYSTEM, POWER ELECTRONIC CIRCUIT, AND BATTERY MODULE
Document Type and Number:
WIPO Patent Application WO/2022/088655
Kind Code:
A1
Abstract:
Disclosed in the present application are a power supply system, a power electronic circuit, and a battery module. The system comprises: a plurality of power electronic circuits; the number of power electronic circuits is equal to the number of phases of the power supply system, and input ends of the plurality of power electronic circuits are respectively connected to a plurality of phases of the power supply system in one-to-one correspondence; each power electronic circuit comprises: a plurality of power conversion circuits connected in series; the plurality of power conversion circuits are arranged in at least two layers in space, the at least two layers comprise a first layer and a second layer; the first layer and the second layer each comprise a plurality of power conversion circuits; the power conversion circuits in the first layer are connected in series to the power conversion circuits in the second layer in a staggered manner, and the power conversion circuits in the first layer being connected in series to the power conversion circuits in the second layer in the staggered manner specifically comprises: at least two power conversion circuits in the first layer are directly connected in series to the power conversion circuits in the second layer. According to the present application, a voltage difference between the power conversion circuits in two adjacent layers is effectively reduced to prevent fire, thereby ensuring safe power supply of the power supply system.
