A system for distributing the weight of a column section during lifting by a crane is provided. The blade includes a profiled contour including a leading edge and a trailing edge as well as a pressure side and a suction side, the profiled contour when being impacted by an incident airflow generating a lift. The phase detector also includes a second flip flop having a data input coupled to an output of the first flip flop and a clock input coupled to the second clock signal. The power converter includes a pair of power-receiving terminals for receiving an AC voltage, thereby converting the AC voltage into a DC voltage. A construction on the surface of the support structure is positioned directly under the source region on the bottom of the JFET die and forms electrical continuity between the JFET source and a second external lead.
