Patent number: 11808793Abstract: A detection device, an inverter, and a detection method are disclosed. The detection device is configured to detect a leakage current flowing through a conductor. The detection device includes a magnetic core, a detection winding and a calibration winding both wound on the magnetic core, a detection circuit, and a calibration circuit. The detection circuit is coupled to the detection winding, and configured to sample a detection signal of the detection winding to obtain a leakage current detection value. The calibration circuit is coupled to the calibration winding, and configured to provide a calibration signal to the calibration winding.Type: GrantFiled: May 11, 2022Date of Patent: November 7, 2023Assignee: DELTA ELECTRONICS (SHANGHAI) CO., LTD.Inventors: Yu-Xi Wang, Jun-Xiong Wu, Bing-Wen Weng, Xuan-Cai Zhu

Patent number: 9231488Abstract: A power converter includes a full-bridge converter circuit and a regulation circuit. The full-bridge converter circuit includes a full-bridge circuit having a first and a second input terminals and a first and a second output terminals. The regulation circuit is bridged across the first and the second input terminals of the full-bridge circuit and connected to the first output terminal of the full-bridge circuit. The regulation circuit is configured for operatively regulating an output voltage across the first and the second output terminals of the full-bridge circuit by cooperating with the full-bridge converter circuit, such that the output voltage across the first and the second output terminals of the full-bridge circuit has more than three voltage levels. A method for controlling a power converter is also disclosed herein.Type: GrantFiled: January 2, 2013Date of Patent: January 5, 2016Assignee: DELTA ELECTRONICS, INC.Inventors: Xuan-Cai Zhu, Bing-Wen Weng
