Power Output Apparatus And Vehicle Having The Same

A power output apparatus, comprising:

• first and second motor generators;
• first and second inverters connected to said first and second motor generators, respectively;
• a control device controlling operations of said first and second inverters to drive said first and second motor generators and to generate an AC voltage across neutral points of said first and second motor generators;
• an AC output cutoff circuit provided between an output line pair connected to the neutral points of said first and second motor generators and an output terminal for outputting said AC voltage to an AC load;
• and
• a leakage detecting device detecting presence/absence of leakage based on currents flown through said output line pair in opposite directions from each other by a voltage difference generated between said neutral points when said AC load receives supply of said AC voltage from said neutral points via said output line pair, and generating a cutoff command upon detection of the leakage to cause said AC output cutoff circuit to cut off output of said AC voltage and to stop the operation of at least one of said first and second inverters.
