HYBRID WORK MACHINE AND METHOD OF CONTROLLING HYBRID WORK MACHINE
A hybrid work machine includes: a generator motor that is connected to a drive shaft of an internal combustion engine; a storage battery that stores at least power generated by the generator motor; a motor that is driven by at least one of the power generated by the generator motor and power stored in the storage battery; a booster that includes two bridge circuits each having a plurality of switching elements and is provided between the generator motor as well as the motor and the storage battery; and a booster control unit that sets a phase difference between voltages output by the bridge circuits to be zero during standby in which servo control on both the generator motor and the motor is turned off.
