Abstract: The present invention relates to a de-icing arrangement (400) and a method for de-icing a structural element (610). The de-icing arrangement comprises at least one electromagnetic actuator (404),a capacitive storage bank (403),a control unit (401) arranged to provide an excitation pulse to the at least one electromagnetic actuator,and a charging circuit (402) arranged to charge the capacitive storage bank (403). The at least one electromagnetic actuator (404) is arranged to expand in at least one direction when fed with the excitation pulse. The at least one electromagnetic actuator (404) is arranged in abutting relation to said structural element so as to apply a mechanical force caused by the expansion on the structural element. The control unit (401) is arranged to control current discharge of the capacitive storage bank into the at least one electromagnetic actuator so as to abort the excitation pulse at a predetermined timing after start of the pulse.

Abstract: The present invention relates to a de-icing arrangement (300) and a method for de-icing a structural element. The de-icing arrangement comprises at least one electromagnetic actuator (304), a capacitive storage bank (303), a control unit (301) arranged to provide an excitation pulse (p) to the at least one electromagnetic actuator, and a charging circuit (302) arranged to charge the capacitive storage bank (403). The at least one electromagnetic actuator (304) is arranged to expand in at least one direction when fed with the excitation pulse. The at least one electromagnetic actuator (304) is placed in relation to said structural element so as to apply a mechanical force caused by the expansion on the structural element. The capacitive storage bank (303) comprises a plurality of selectable capacitors of different capacitance and the control unit (301) is arranged to select at least one capacitor for charging having a total capacitance such that current discharge of the capacitive storage bank into the at least one electromagnetic actuator generates a desired distribution between heat and mechanical power.
