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: 11213908Abstract: The wire feeding device that feeds welding wire W from the wire source to the welding torch is disposed between the wire source and the welding torch and is configured to temporarily accommodate the welding wire W fed from the wire source and to feed the accommodated welding wire W to the welding torch. In the case where feeding of welding wire W is abnormally stopped, if the acceptance unit accepts instructions for increasing or decreasing, the wire feeding device controls the speed of feeding welding wire W fed by the first feeding part or the second feeding part so that a difference is generated in the feeding speed of the first feeding part and the second feeding part and the accommodated amount of welding wire W is in a range from the lower limit of normal to an upper limit of normal.Type: GrantFiled: January 17, 2019Date of Patent: January 4, 2022Assignee: DAIHEN CorporationInventors: Hirokazu Kawai, Futoshi Nishisaka, Haruhiko Manabe, Kazutoshi Nagami, Masahiro Inoue, Hisao Miyahara, Akio Yoshinaga

Patent number: 9143048Abstract: A power supply device that is applicable to both 200 V and 400 V series input power by switching the operation of an auxiliary switching circuit with a switching switch. When a relatively large output is requested, PWM control is performed to adjust the on pulse width of a control pulse signal provided to switching elements of an inverter circuit and an auxiliary switching circuit, which is operated in cooperation with the inverter circuit. When a relatively small output is requested, PSM control is performed to adjusting a phase difference of two control pulse signals provided to the same set of switching elements in the inverter circuit.Type: GrantFiled: November 12, 2012Date of Patent: September 22, 2015Assignee: Daihen CorporationInventors: Tetsuya Etoh, Haruhiko Manabe

Patent number: 8804375Abstract: A power supply that performs output PWM control and PSM control. The PWM control is performed when the required output is such that a control signal is set with a larger ON pulse width than a predetermined narrow pulse width allowing for sufficient activation of switching elements in an inverter circuit and an auxiliary switching circuit. The PSM control is performed when the required output is such that the control signal for each switching element is set with a smaller ON pulse width than the predetermined narrow pulse width. The PSM control adjusts the phase of a control pulse signal so that the ON pulse is fixed to the predetermined narrow pulse width.Type: GrantFiled: November 29, 2011Date of Patent: August 12, 2014Assignee: Daihen CorporationInventors: Haruhiko Manabe, Tetsuya Etoh, Hirotsune Tajima, Kazutoshi Nagami, Masayoshi Kureha
