Zusammenfassung:To provide a power source integration system with a motor driving function and a battery charging and discharging function.SOLUTION: A power source integration system with a driving function and a battery charging and discharging function includes a motor, a power source integration circuit, and a battery connected to the power source integration circuit. The power source integration circuit has a multiphase bridge arm. The bridge arm of each phase includes an upper switch and a lower switch. The bridge arm of each phase includes an inverter connected to a coil of each phase of the motor, and a charger including a pre-stage DC conversion circuit and the upper switch and the lower switch of the bridge arm of at least one phase of the multiphase bridge arm to be shared with the inverter. The power source integration circuit receives DC power source supplied from a DC power source device. The charger charges the battery by converting the DC power source of the DC power source device. The battery supplies power necessary to drive the motor through the inverter.SELECTED DRAWING: Figure 1 【課題】モータ駆動機能と電池充放電機能とを有する電源統合システムを提供する。【解決手段】駆動機能と電池充放電機能とを有する電源統合システムは、モータと、電源統合回路と、前記電源統合回路に接続される電池とを含み、前記電源統合回路は、多相ブリッジアームを有し、各相のブリッジアームが上スイッチと下スイッチとを含み、前記各相のブリッジアームが前記モータの各相の巻線に接続されるインバータと、前段直流変換回路と、前記インバータと共用する前記多相ブリッジアームの少なくとも一相のブリッジアームの前記上スイッチ及び前記下スイッチと、を含む充電器と、を備え、前記電源統合回路は、直流電源装置から供給される直流電源を受け、前記充電器は、前記直流電源装置の前記直流電源を変換して前記電池を充電し、前記電池は、前記インバータを介して前記モータを駆動するのに必要な電力を供給する。【選択図】図1
