Power output apparatus and vehicle having the same

摘要

A power output apparatus generates a commercial AC voltage across neutral points of first and second motor generators. The power output apparatus includes a leakage detecting device, and upon detection of leakage by the leakage detecting device, causes an AC output cutoff circuit to operate and also shuts down one or both of the first and second motor generators according to the operational states at the time. Further, the leakage detecting device performs checking of the leakage detecting function in response to a test signal from a control device, before outputting the commercial AC voltage.
