Publication number: 20240151360Abstract: A hydrogen supply method includes a two-side heat exchange mode in which both introducing a second fluid into a hydrogen storage part after the second fluid exchanges heat with a first fluid in a second heat exchanger in a state in which a compressor is driven to compress the first fluid and introducing the second fluid into the hydrogen storage part after the second fluid is heated or cooled in the thermal device are performed. The method also includes a one-side heat exchange mode in which one of introducing the second fluid into the hydrogen storage part after the second fluid exchanges heat with the first fluid in the second heat exchanger in a state in which the compressor is driven to compress the first fluid and introducing the second fluid into the hydrogen storage part after the second fluid is heated or cooled in the thermal device is performed.Type: ApplicationFiled: August 30, 2023Publication date: May 9, 2024Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: Ho Young Jeong, Hoon Mo Park, Kyung Moon Lee, Yeon Ho Kim, Ji Hye Park, Jae Yeon Kim, Dong Hoon Nam

Patent number: 10063091Abstract: Provided is a standby power saving circuit. A switching element is arranged between a SMPS supplying power to a load and a power supply unit supplying power to the SMPS to block power supply to SMPS in a standby mode by turning off the switching element in the standby mode and to supply power to the SMPS only when an electronic device operates. In addition, a circuit supplying a power to a load and a circuit for supplying a standby power are separated, a power storage unit for supplying a driving power to the switching element is arranged inside the circuit for supplying the standby power, and if a charged power of the power storage unit is lower than a reference value, power is supplied to only the circuit for supplying the standby power, and the power storage unit is charged. Therefore it is possible to reduce a standby power.Type: GrantFiled: January 9, 2015Date of Patent: August 28, 2018Assignee: DAJAE TECH CO., LTDInventor: Yeon Moon Jeong

Publication number: 20110215731Abstract: Provided is an LED illumination driving apparatus. When dimming is performed in the LED illumination apparatus, the power voltage level supplied to an LED module is selectively adjusted according to illuminance to prevent the flicker phenomenon occurring due to an excessive decrease in a duty ratio of a PWM control signal at a dimming time in the related art. More specifically, if the set illuminance is decreased by a user, the duty ratio of the PWM control signal is decreased, so that the illuminance of the LED illumination is decreased. When the duty ratio of the PWM control signal is decreased, if the user decreases the illuminance below a predetermined level corresponding to a threshold duty ratio where the flicker phenomenon occurs, the power voltage level transmitted to the LED module is decreased. The duty ratio is allowed to be increased again by the duty ratio corresponding to the decrease in the power voltage level, and after that, the duty ratio is allowed to be decreased again.Type: ApplicationFiled: February 28, 2011Publication date: September 8, 2011Applicant: LIGHTGREEN CONCEPT CO., LTD.Inventors: Yeon Moon JEONG, Kang Wha Chung
