Patent number: 11101738Abstract: A power converter includes a PFC circuit, a first capacitor, a second capacitor and an auxiliary circuit. The PFC circuit provides a first intermediate voltage to the first capacitor. The auxiliary circuit includes a first auxiliary branch circuit and a second auxiliary branch circuit. When the first auxiliary branch circuit is enabled, and the first intermediate voltage is transmitted to the second capacitor through the first auxiliary branch circuit. When the second auxiliary branch circuit is enabled, the first intermediate voltage is boosted by the second auxiliary branch circuit, so that a second intermediate voltage is provided by the second capacitor. While an operation state of the load is switched between a light load condition and a heavy load condition, one of the first auxiliary branch circuit and the second auxiliary branch circuit is selectively enabled.Type: GrantFiled: June 12, 2020Date of Patent: August 24, 2021Assignee: DELTA ELECTRONICS, INC.Inventors: Junlai Huang, Youzhun Cai, Dominik Reinhard Beinlich, Lingfeng Jiang
