To increase a degree of freedom of arrangement while maintaining reliability of operations.SOLUTION: A power supply device 42 includes a first conversion circuit 43c, a first control circuit 43d, a second conversion circuit 44a, a second control circuit 44b, a first substrate 431, and a second substrate 441. On the first substrate 431, a plurality of first circuit components 432 constituting the first conversion circuit 43c and the first control circuit 43d are mounted. On the second substrate 441, a plurality of second circuit components 442 constituting the second conversion circuit 44a and the second control circuit 44b are mounted. The first control circuit 43d controls the first conversion circuit 43c by power supply from the second control circuit 44b. The second control circuit 44b monitors an AC power to be input and supplies power to the first control circuit 43d only when the AC power is input to the first conversion circuit 43c.SELECTED DRAWING: Figure 1 【課題】動作の信頼性を維持しつつ、配置の自由度を高めること。【解決手段】電源装置４２は、第１変換回路４３ｃと第１制御回路４３ｄと第２変換回路４４ａと第２制御回路４４ｂと第１基板４３１と第２基板４４１とを備えている。第１基板４３１には、第１変換回路４３ｃ及び第１制御回路４３ｄを構成する複数個の第１回路部品４３２が実装される。第２基板４４１には、第２変換回路４４ａ及び第２制御回路４４ｂを構成する複数個の第２回路部品４４２が実装される。第１制御回路４３ｄは、第２制御回路４４ｂから給電されることで第１変換回路４３ｃを制御する。第２制御回路４４ｂは、入力される交流電力を監視し、交流電力が第１変換回路４３ｃに入力されているときのみ、第１制御回路４３ｄに給電する。【選択図】図１
