Publication number: 20240055993Abstract: A converter comprises a first circuit part and a second circuit part configured to be electrically connected with each other. Each circuit part comprises two or more switches configured to be switched for the power conversion, the switches being semiconductor switches. The two or more switches of the first circuit part are configured for a first switching operation of the first circuit part. The two or more switches of the second circuit part are configured for a second switching operation of the second circuit part. The first switching operation causes a greater electrical power loss compared to the second switching operation. The two circuit parts are configured such that the first circuit part is configured to operate at a higher operating temperature compared to the second circuit part.Type: ApplicationFiled: October 27, 2023Publication date: February 15, 2024Inventors: Piniwan Thiwanka Bandara Wijekoon, Sebastian Rosado, Zhaohui Wang

Patent number: 10291111Abstract: A system and method includes parallel power converters, at least one current sensor, and a first feedback control circuit. A first power converter is configured to convert a first input power to a first output power, and is controlled using pulse width modulation having a first switching period. One or more second power converters are connected in parallel with the first power converter and configured to convert a second input power to a second output power. The first output power and the second output power are provided to a load. The at least one current sensor is positioned to sense first output current of the first output power, and the first feedback control circuit is configured to calculate a first metric based on the first sensed current at each of a plurality of first edges of each half switching period of the first switching period, and at intermediate points between each of the plurality of first edges.Type: GrantFiled: March 23, 2018Date of Patent: May 14, 2019Assignee: Hamilton Sundstrand CorporationInventors: Sebastian Rosado, Virgilio Valdivia Guerrero, Laura Albiol-Tendillo
