Patent number: 11943858Abstract: The present disclosure relates to an induction heating apparatus and a method of controlling the same. A controller of the induction heating apparatus according to the present disclosure may set an operation mode of an inverter circuit to a half bridge mode when a required power value of a working coil is set to a value less than a reference power value such that a driving frequency of the working coil decreases while an actual power value of the working coil is kept the same as the required power value. Additionally, the controller of the induction heating apparatus may adjust a duty ratio of a switching signal input to a switching element included in the inverter circuit, thereby adjusting the actual power value of the working coil.Type: GrantFiled: March 31, 2021Date of Patent: March 26, 2024Assignee: LG ELECTRONICS INC.Inventors: Gwangrok Kim, Ho Yong Jang, Jung Youn Lee, Seongkyu Song

Publication number: 20230141390Abstract: The present disclosure relates to an induction heating device and a control method thereof. In one embodiment, at a time of a simultaneous operation of a first working coil operating at a first driving frequency and a second working coil operating at a second driving frequency, control for removing interference noise is performed based on a difference between the first driving frequency and the second driving frequency. An induction heating device of one embodiment may adjust the duty ratio of a switching signal provided to a first inverter circuit after adjusting the first driving frequency to adjust the actual output value of the first working coil to a value the same as the required output value of the first working coil.Type: ApplicationFiled: March 26, 2021Publication date: May 11, 2023Inventors: Gwangrok KIM, Ho Yong JANG, Jung Youn LEE, Seongkyu SONG
