Electro-hydraulic system i.e. vehicle steering system, has motor-pump-aggregates connected to voltage source that provides mains voltage, and electrical connection provided for stabilization of supply voltage of each motor-pump-aggregate

摘要

The system (10) has motor-pump-aggregates (16, 18) connected to a voltage source (26) e.g. vehicle battery, that provides a mains voltage. The motor-pump-aggregates are designed for providing a supply voltage that corresponds to a fraction of the mains voltage. An electrical connection (12) is provided for stabilization of the supply voltage of each motor-pump-aggregate. A high frequency switch is arranged between a voltage divider circuit (30) and the motor-pump-aggregates, where the circuit exhibits voltage divider elements (31, 32). An independent claim is also included for a method for controlling an electrical voltage for motor-pump-aggregates of an electro-hydraulic system.
