Publication number: 20250023490Abstract: A power supply system, a three-phase inverter, and a controller and a control method for a three-phase inverter. In the power supply system, after a low-voltage failure occurs in a power grid, a three-phase inverter outputs a first positive-sequence reactive current to the power grid through low voltage ride-through. When a voltage of at least one of three alternating currents output by the three-phase inverter is greater than a preset threshold, the three-phase inverter outputs a small second positive-sequence reactive current to the power grid through the three alternating currents, to reduce a voltage at an output end of the three-phase inverter and improve stability of the entire power supply system.Type: ApplicationFiled: September 23, 2024Publication date: January 16, 2025Applicant: Huawei Digital Power Technologies Co., Ltd.Inventors: Qilei CHEN, Zhangping Shao, Xinyu Yu, Kai Xin
