  • Patent number: 11943858
    Abstract: 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.

  • Patent number: 11817889
    Abstract: A communication method and an apparatus in a wireless communication system are provided. The communication method includes identifying, by a first satellite including a session management function within a space core network (SCN), a protocol data unit (PDU) session establishment request from a UE, selecting, by the first satellite, a satellite gateway for communicating with a ground gateway, and requesting, by the first satellite, the satellite gateway to allocate a port number which is matched to identification information of a first general packet radio service (GPRS) tunneling protocol-user (GTP-U) tunnel to be used for transmission and reception of packets for a PDU session requested by the UE in a path between a satellite base station which the UE accesses and the satellite gateway, wherein the packets are transmitted or received to and from a terrestrial core network (TCN) by using address information which is converted based on the port number.

  • Publication number: 20230141390
    Abstract: 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.
