PROBLEM TO BE SOLVED: To provide a vehicle auxiliary power supply device configured to be capable of implementing further downsizing.SOLUTION: A vehicle auxiliary power supply device 100A comprises: a converter device 2 that is mounted on an electric vehicle and converts DC power supplied from a DC power supply 1 into desired DC power; and a three-phase inverter 3A that converts DC power supplied from the converter device 2 into sinusoidal three-phase AC power to supply the AC power to a load 4. The three-phase inverter 3A includes a switching element that is formed using a wide bandgap semiconductor, is driven at a switching frequency equal to or higher than 50 kHz; a filter reactor 5 and a filter capacitor 6 are provided on the output side of the three-phase inverter 3A.SELECTED DRAWING: Figure 1 【課題】更なる小型化を実現可能に構成される車両用補助電源装置を提供すること。【解決手段】電気車に搭載され、直流電源１から供給される直流電力を所望の直流電力に変換するコンバータ装置２と、コンバータ装置２から供給される直流電力を正弦波状の三相の交流電力に変換して負荷４に供給する三相インバータ３Ａとを備えた車両用補助電源装置１００Ａであって、三相インバータ３Ａのスイッチング素子はワイドバンドギャップ半導体によって形成され、５０ｋＨｚ以上のスイッチング周波数で駆動され、三相インバータ３Ａの出力側にはフィルタリアクトル５およびフィルタコンデンサ６を設けた。【選択図】図１
