  "textContent": "[Object] To downsize a hybrid construction machine and to make a rotation electric motor of the construction machine operable immediately following the start-up of an engine. [Means to Achieve the Object] A generator 5 connected to an engine 2 generates AC power. A converter 5 is connected to the generator 5, and an inverter 32 for controlling the electric power to a rotation electric motor 18 is connected to the converter 5. The converter 30 and the inverter 32 are formed of IGBTs connected between power supply lines 34r, 34s, 34t and the rotation electric motor 18. The AC power from the generator 5 is converted directly to AC power which can be supplied to the rotation electric motor 18.",
