Zusammenfassung: | The present invention relates to a power supplying apparatus. The power supplying apparatus comprises: a power supplying unit (10) which outputs an alternating current; an outputting unit (20) connected to a feeding line; and an adjusting unit (31) which adjusts a capacitance of a feeding circuit between the power supplying unit (10) and the outputting unit (20). The adjusting unit (31) includes: a first capacitor (41); a second capacitor (42); and a circuit switching device (4). The circuit switching device (4) is configured to switch between a series connection status, in which the first capacitor (41) and the second capacitor (42) are connected in series between the power supplying unit (10) and the outputting unit (20), and a parallel connection status in which the first capacitor (41) and the second capacitor (42) are connected in parallel between the power supplying unit (10) and the outputting unit (20). Realized is the power supplying apparatus capable of appropriately adjusting the capacitance of the feeding circuit according to a length of the feeding line.
전원 장치는, 교류 전류를 출력하는 전원부(10)와, 급전선에 접속되는 출력부(20)와, 전원부(10)와 출력부(20) 사이의 급전 회로의 커패시턴스를 조정하는 조정부(31)를 구비한다. 조정부(31)는, 제1 커패시터(41)와, 제2 커패시터(42)와, 회로 전환 기구(4)를 구비한다. 회로 전환 기구(4)는, 제1 커패시터(41)와 제2 커패시터(42)를 전원부(10)와 출력부(20) 사이에 직렬로 접속하는 직렬 접속 상태와, 제1 커패시터(41)와 제2 커패시터(42)를 전원부(10)와 출력부(20) 사이에 병렬로 접속하는 병렬 접속 상태로 전환하도록 구성되어 있다. |
