Title:

CONTROL DEVICE FOR HYBRID CONSTRUCTION MACHINE

Document Type and Number:

WIPO Patent Application WO/2011/135691

Kind Code:

A1

Abstract:

A hybrid construction machine is made compact, and an electric swing motor thereof is driven immediately after an engine is started. A generator (5) connected to an engine (2) generates alternating current power. A converter (30) is connected to the generator (5). An inverter (32) which controls power to the electric swing motor (18) is connected to the converter (30). The converter (30) and the inverter (32) comprise IGBTs which are disposed between the electric swing motor (18) and power supply lines (34r, 34s, 34t) for the generator (5). These IGBTs convert the alternating current power of the generator (5) directly into alternating current power which can be applied to the electric swing motor (18).
