Patent number: 11404203Abstract: A magnetic unit is presented. The magnetic unit includes a magnetic core. The magnetic core includes a first limb and a second limb disposed proximate to the first limb, where a gap is formed between the first limb and the second limb. The magnetic unit further includes a first winding wound on the first limb. Moreover, the magnetic unit includes a conductive element disposed facing an outer periphery of the first winding, where the conductive element is configured to control a fringing flux generated at the gap. Further, the magnetic unit includes a heat sink operatively coupled to the conductive element, where the conductive element is further configured to transfer heat from at least one of the conductive element and the first winding to the heat sink. Moreover, a high frequency power conversion system and a method of operation of the magnetic unit is also presented.Type: GrantFiled: June 13, 2018Date of Patent: August 2, 2022Assignee: General Electric CompanyInventors: Cong Li, Anoop Jassal, Naveenan Thiagarajan, Satish Prabhakaran, Kum-Kang Huh, Jiangbiao He, Xiaosong Kang, Ruxi Wang

Patent number: 7564213Abstract: A battery control system for controlling a state of charge of a hybrid vehicle battery includes a detecting arrangement for determining a vehicle operating state or an intended vehicle operating state and a controller for setting a target state of charge level of the battery based on the vehicle operating state or the intended vehicle operating state. The controller is operable to set a target state of charge level at a first level during a mobile vehicle operating state and at a second level during a stationary vehicle operating state or in anticipation of the vehicle operating in the stationary vehicle operating state. The invention further includes a method for controlling a state of charge of a hybrid vehicle battery.Type: GrantFiled: August 13, 2004Date of Patent: July 21, 2009Assignee: Eaton CorporationInventors: Thomas R. Bockelmann, Kevin D. Beaty, Zhanijang Zou, Xiaosong Kang
