发明名称 Switched actuator control
摘要 The present invention discloses an electromechanical actuator arrangement and a driving device for such an arrangement, having a plurality of drive element to be driven according to a wailing mechanism is provided. The driving device is characterised by an electrical power source (170) and at least two switches (172a, 172b) connected in series between the terminals (177) of the voltage source (170). An element terminal (178) is connected to a point (175) between said switches (172a, 172b), and a motor phase (174) of the actuator arrangement is connected to the element terminal (178). A control unit (171) is connected to control the switches (172a, 172b) in order to charge/discharge the drive elements. A charge control is thereby achieved by the use of the two switches (172a, 172b).
