Patent number: 11642735Abstract: A power supply system includes multiple power supply devices including a first power supply device and a second power supply device that are connected in common to a load. The first power supply device calculates control information for controlling voltage or current to be output to the load and source information for obtaining the control information, and controls the output to the load based on the calculated control information while transmitting the source information to the second power supply device. The second power supply device receives the source information transmitted from the first power supply device, calculates control information based on the received source information, and controls the output to the load while detecting current to be output from itself to the load and transmitting current information to the first power supply device.Type: GrantFiled: April 16, 2018Date of Patent: May 9, 2023Assignee: DAIHEN CorporationInventors: Hirokazu Kawai, Songjie Hou, Futoshi Nishisaka, Haruhiko Manabe

Patent number: 11370052Abstract: An arc welding system of a consumable electrode type comprises: a wire feeding device that feeds welding wire from a wire feeding source to a welding torch; and a power supply device that supplies electric power between the welding wire fed to the welding torch and a base material, the system being configured to weld the base material by arc generated by the supplied electric power. The wire feeding device is provided with: an intermediate wire feeding source that is disposed between the wire feeding source and the welding torch and is configured to temporarily accommodate the welding wire fed from the wire feeding source and to feed the accommodated welding wire to the welding torch; a pull-out feeding part that feeds the welding wire at the wire feeding source to the intermediate wire feeding source; and a push-out feeding part that feeds the welding wire accommodated in the intermediate wire feeding source to the welding torch.Type: GrantFiled: March 9, 2017Date of Patent: June 28, 2022Assignee: DAIHEN CorporationInventors: Masahiro Inoue, Yukiya Morita, Hisao Miyahara, Hirokazu Kawai, Songjie Hou, Hayato Baba, Hideo Shiozaki, Tetsuo Era, Tomoyuki Ueyama

The first power supply device calculates control information for controlling voltage or current to be output to the load and controls the output to the load based on the calculated control information while transmitting the control information to the second power supply device. The second power supply device receives the control information and controls the output to the load based on the received control information while detecting current to be output from its own device to the load and transmitting current information to the first power supply device. The first power supply device receives the current information transmitted from the second power supply device and calculates control information based on the received current information and the current and voltage detected by its own device.Type: GrantFiled: May 23, 2017Date of Patent: June 29, 2021Assignee: DAIHEN CorporationInventors: Hirokazu Kawai, Songjie Hou, Hideo Shiozaki, Haruhiko Manabe, Satoru Hata, Hiroyasu Mondori, Kazuki Yoshida
