  • High-Voltage Three-Phase Four-Bridge-Arm Topology Structure and Inverter
    Publication number: 20250062699
    Abstract: Disclosed are a high-voltage three-phase four-bridge-arm topology structure and an inverter. The topology structure includes four bridge-arm circuits and a converter; one end of first bridge-arm circuit is connected to an A-phase high voltage line and the other end is connected to a first conversion module, one end of second bridge-arm circuit to a B-phase high voltage line and the other end to a second conversion module; one end of third bridge-arm circuit to a C-phase high voltage line and the other end to a third conversion module; one end of fourth bridge arm circuit to a ground line and the other end to a fourth conversion module, and the fourth bridge arm circuit is used to perform voltage compensation on the output voltages of the first bridge arm circuit, second bridge arm circuit, and third bridge arm circuit when the three phase high voltage lines are unbalanced.
