Zusammenfassung:	To provide a power supply unit integrating the functions of a plurality of power conversion devices, capable of suppressing thermal interference among the power conversion devices while performing downsizing.SOLUTION: A power supply unit accommodates a main DC/DC converter and an AC charger (a charging circuit, a sub DC/DC converter) in a housing. The main DC/DC converter and the sub DC/DC converter are placed on the same layer in the housing. The charging circuit is placed on a layer different from the main DC/DC converter and the sub DC/DC converter. The main DC/DC converter and the sub DC/DC converter placed on the same layer in the housing are controlled to operate exclusively.SELECTED DRAWING: Figure 7 【課題】複数の電力変換装置の機能を統合した電力変換ユニットにおいて、小型化を図りつつ、電力変換装置間の熱干渉を抑制することである。【解決手段】電力供給ユニットは、メインＤＣ／ＤＣコンバータおよびＡＣ充電器（充電回路、サブＤＣ／ＤＣコンバータ）を筐体に収容している。メインＤＣ／ＤＣコンバータおよびサブＤＣ／ＤＣコンバータは、筐体内の同一の階層に配置される。充電回路は、メインＤＣ／ＤＣコンバータおよびサブＤＣ／ＤＣコンバータとは異なる階層に配置される。筐体内の同一の階層に配置されたメインＤＣ／ＤＣコンバータおよびサブＤＣ／ＤＣコンバータは、排他的に動作するように制御される。【選択図】図７
