    Abstract: A vibration welding system has a pair of electromagnets coupled to a first workpiece support for effecting reciprocating movement of the first workpiece support relative to a second workpiece support, and an electrical drive system coupled to the electromagnets for successively energizing and de-energizing the electromagnets out of phase with each other to effect the reciprocating movement of the first workpiece support. The drive system includes a source of DC current; multiple controllable electronic switching devices for controllably coupling the source to, and de-coupling the source from, each of the electromagnets; current sensors coupled to the electromagnets and producing signals representing the currents supplied to the electromagnets; and control circuitry coupled to the electronic switching devices and receiving the signals produced by the current sensors for turning the switching devices on and off to control the energizing and de-energizing of the electromagnets to effect reciprocating movement of the first workpiece support.

    Abstract: The present invention relates to an output stage for matching an AC voltage signal from an ultrasound generator to a converter connectable to the output stage, wherein the output stage has two input terminals for receiving the AC voltage generated by the ultrasound generator and two output terminals for outputting a matched AC voltage signal, as well as an output transformer with a primary coil having a number of turns n
    1 and a secondary coil having a number of turns n2. The output transformer has a main inductance LH and a leakage inductance Lσ, the two input terminals being connected via the primary coil and the two output terminals via the secondary coil. In order to specify an output transformer that allows an economical and compact matching of a generator output to the converter input, according to the invention a filter capacitor Cp is provided, which either connects the two output terminals in parallel to the secondary coil or connects an output terminal to a tap of the secondary coil or is connected to a filter inductor with n3 turns, which is inductively coupled to the primary and the secondary coil.
