<p>#CMT# #/CMT# A hybrid drive system has a current generating system (3) with a combustion engine (1), which drives a three-phase current generator (2), which transfers its generated electrical energy to a DC voltage link (4) which transfers the electrical energy via one- or more inverters (6) to the drive lift and auxiliary motors (7-9) and is connected to a static electric energy reservoir (10). An electronic device (15) control the individual components and units and is connected to the DC voltage link (4) and to a further electric energy reservoir, which is designed as a temporary power store (12) and consists of one or more interconnected ultra capacitors (13). #CMT# : #/CMT# An independent claim is also included for a method for operating a hybrid drive system. #CMT#USE : #/CMT# For portal stacker vehicle i.e. straddle carrier for seaports and container terminals. #CMT#ADVANTAGE : #/CMT# Allows the current generating equipment used, especially the diesel generator, to be made considerably smaller and lighter. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# A block circuit diagram of the hybrid drive system is given. 1 : Diesel engine 2 : Three-phase current generator 3 : Current generating system 4 : Busbar 5 : Intermediate circuit capacitors 6 : Inverter 8 : Lifter motor 10 : Power reservoir with batteries 11 : Charge/discharge control 15 : Electronic control.</p> |
