Actuating drive and emergency energy supply device

Номер: US0007566981B2
Принадлежит: Bosch Rexroth AG, BOSCH REXROTH AG

An actuating drive for a rotor blade in a wind power installation is provided with an electric motor and a frequency converter which has a rectifier that is to be fed from a power supply system, a link connected to the rectifier, and a d.c.-to-a.c. inverter for feeding the motor, the link carrying a specified nominal operating voltage in a network-fed normal operation of the frequency converter. Furthermore, an auxiliary energy supply device is provided that is connected to the link. The auxiliary energy supply device includes and energy store which makes available a support voltage that amounts to less than 80% of the nominal operating voltage of the link. A diode is connected between the energy store and the link, and is arranged, with regard to its forward direction, in such a way that it feeds a support voltage from the energy store into the link if the link voltage falls below the support voltage. The diode prevents a current flow between the energy store and the link if the link voltage ...

The diode prevents a current flow between the energy store and the link if the link voltage is greater than the support voltage. A charging device for the energy store has a lower charging voltage than the nominal operating voltage of the link.

Actuator and emergency power supply

Номер: EP1739807A2
Принадлежит: Bosch Rexroth AG

A diode (36) prevents current flow between accumulators (22,24,26,28) and an intermediate circuit (14) if the intermediate circuit voltage is larger than the supporting voltage. The supporting voltage is less than 80 percent of the rated voltage of the intermediate circuit. A charging circuit (54) provides a charging voltage less than the rated voltage of the intermediate circuit to the accumulators. The AC mains (10) powers an electric motor (16) through an electric rectifier (11) and the intermediate circuit. An emergency power supply mechanism (20) that includes the accumulators and the diode supplies supporting current from the accumulators to the intermediate circuit if the intermediate circuit voltage falls below the supporting voltage. An independent claim is also included for an emergency power supply mechanism.
