Patent number: 10071637Abstract: A pulse width modulation resonance converter is provided that includes a transformer and a switching unit including first to fourth switches electrically connected to a primary coil of the transformer and configured to convert a DC voltage into an AC voltage by a switching operation of the first to fourth switches in which each switch is switched from an off state to an on state when a voltage difference between both ends is about 0. Additionally, a rectifying unit includes an output capacitor, first to fourth diodes electrically connected to a secondary coil of the transformer, and a resonance tank having a resonance capacitor and a resonance inductor which are electrically connected to the secondary coil of the transformer. The plurality of switches connected to the primary side of the transformer perform the zero-voltage switching using the magnetized inductance of the primary side to minimize the switching loss.Type: GrantFiled: November 16, 2014Date of Patent: September 11, 2018Assignees: Hyundai Motor Company, Myongji University Industry and Academia Cooperation Foundation, Kia Motors CorporationInventors: Jong Pil Kim, Seok Joon Kim, Sam Gyun Kim, Woo Young Lee, June Young Lee, Byung Kwon Lee

Patent number: 9074570Abstract: Disclosed herein is a method and a system for controlling a generation output of a starter generator connected to an engine to transmit a rotary force in a hybrid electric vehicle. The method includes receiving, by a controller, vehicle state information for determining a driving mode of the vehicle after the vehicle starts, and determines the driving mode requiring an increase of the generation output from the vehicle state information; determining, by the controller, a need for the increase of the generation output to control a generation output variable for each driving mode; determining, by the controller, a torque command and a torque application time corresponding to a required output for each driving mode of the vehicle to control the generation output variable; and applying, by the controller, the determined torque command for the determined application time to control the generation output of the starter generator.Type: GrantFiled: November 28, 2012Date of Patent: July 7, 2015Assignee: Hyundai Motor CompanyInventors: Hyun Kim, Kyung Ha Kim, Jae Hyuk Suh, Seung Woo Ha, Yeon Ho Kim, Sam Gyun Kim

Publication number: 20150042159Abstract: An integrated converter and method are provided that combine an onboard charger and a low voltage direct current converter. The integrated improves the charging efficiency of the battery of a vehicle and supplies the high density power to an electronic device load. The charging efficiency of the high voltage battery and electricity transmitting efficiency to the low voltage converter is improved using the integrated converter. Furthermore, the low voltage converter receives high density power since the low voltage converter is input with a substantially stable voltage from the integrated converter.Type: ApplicationFiled: December 30, 2013Publication date: February 12, 2015Applicant: Hyundai Motor CompanyInventors: Jongpil Kim, Seungwoo Ha, Sam Gyun Kim, Woo Young Lee

Publication number: 20140375155Abstract: A motor generator for a vehicle includes a housing having a through hole along a central axis thereof, with a protrusion protruding outwards along a circumference of the through hole. A rotating shaft is disposed in the housing in such a way that a first end thereof is exposed outside through the through hole. A pulley is disposed outside the housing in such a way that the first end of the rotating shaft is inserted into and coupled to a central portion of the pulley. A rim of the pulley is surrounded by the protrusion and a central portion of the pulley passes through the through hole, so that a watertight flange having a larger diameter than the through hole is disposed in the housing.Type: ApplicationFiled: November 18, 2013Publication date: December 25, 2014Applicants: KIA MOTORS CORPORATION, HYUNDAI MOTOR COMPANYInventors: Hyun KIM, Jae Hyuk SUH, Sam Gyun KIM, Seung Woo HA

Publication number: 20140217843Abstract: A motor having a cooling structure includes a rotor fixed to a rotatable motor shaft, a rotor coil formed adjacent the rotor, a coil protection cover disposed adjacent the rotor coil, mounted in the motor shaft, and having a coolant chamber filled with a coolant. The motor further includes a stator fixed adjacent an exterior circumference of the rotor and may include a cover in which one end portion of the motor shaft is rotatably penetrated having a cooling pin at an internal side surface opposite one side surface of the coil protection cover. The coolant filled in the coolant chamber of the coil protection cover receives heat generated in the rotor coil, and, by effectively emitting the heat to the outside through the cooling pin formed in a rear cover, durability of the entire motor can be improved, and failure of peripheral parts can be prevented.Type: ApplicationFiled: July 18, 2013Publication date: August 7, 2014Inventors: Jae Hyuk SUH, Hyun KIM, Sam Gyun KIM, Seung Woo HA
