发明名称 Mobile working machine
摘要 A mobile working machine includes an energy source, a storage circuit for storing electrical energy, a first electronic power converter stage between the storage circuit and the energy source, an electrical machine for driving actuators, a second electronic power converter stage between the storage circuit and the electrical machine, and a control system for controlling the first electronic power converter stage responsive to the power taken by the second electronic power converter stage from the storage circuit, the control system providing a control signal path from the storage circuit to the first electronic power converter stage. The signal processing properties of the control signal path are dependent on the electrical energy stored by the storage circuit in order to allow the electrical energy to vary, but within desired limits, so as to reduce the peak power taken from the energy source.

主权项 1. A mobile working machine comprising: an energy source for supplying electrical energy, a storage circuit for storing electrical energy, a first electronic power converter stage connected between the energy source and the storage circuit, an electrical machine for driving one or more actuators of the mobile working machine, a second electronic power converter stage connected between the storage circuit and the electrical machine, and a control system for controlling the first electronic power converter stage to respond to fluctuation of power taken by the second electronic power converter stage from the storage circuit, the control system providing a control signal path from the storage circuit to the first electronic power converter stage, wherein the control system is arranged to change at least one signal processing property of the control signal path on the basis of the electrical energy stored by the storage circuit so that a control of the electrical energy is slower to respond to changes of the power taken by the second electronic power converter stage when the electrical energy has a first value that is between second and third values than when the electrical energy has either one of the second and third values.
