Hybrid-type construction machine
A disclosed hybrid-type construction machine includes a generator part (12) configured to generate electric energy by the driving force of an engine (11); an inverter (18A) configured to control the generator part (12); an electric power accumulator (120) configured to accumulate the electric energy generated by the generator part (12); a DC bus located between the generator part (12) and the electric power accumulator (120); and a converter (100) configured to control a voltage of the DC bus, wherein when the electric power accumulator (120) having approximately zero electric energy is charged the inverter (18A) of the generator part is not controlled, and a reference value of a voltage command for the DC bus to charge the electric power accumulator is set to be smaller than an induced voltage of the generator part (12).
