Abstract
1. Drive circuit for an actuator and method for driving an actuator. 2.1. The invention relates to a drive circuit for an actuator, said drive circuit having a control unit with means for generating drive signals. 2.2. The invention provides at least one energy store and a charging unit, the charging unit having means for charging the at least one energy store using the drive signals. 2.3. Use for actuators in the automotive sector, for example.
Claims10
Drive circuit (10) for an actuator (12), said drive circuit having a control unit (14) with means for generating drive signals (18, 20), characterized by at least one energy store (28) and a charging unit (24), the charging unit (24) having means for charging the at least one energy store (28) using the drive signals (18, 20).
Method for driving an actuator (12), said method having the following steps:
- at least two types of drive signals (18, 20) are generated, a first type of drive signals (18, 20) being used to charge an energy store (28) and to retain the charge of an energy store (28) and a second type of drive signals (18, 20) being used to trigger the actuator (12).
