Abstract: In a power converter module, a first input area intended to be connected to a first predetermined electric potential (+V) or a second input area intended to be connected to a second predetermined electric potential (−V) can be connected to an output area. At least one group of switches is provided, each group of switches has two semiconductor switch units, and each of the semiconductor switch units has a gate terminal. An input terminal of one of the semiconductor switch units is connected to the first input area, and an input terminal of the other semiconductor switch unit is connected to the second input area. Each of the semiconductor switch units has an output terminal, which is connected to the output area. The two semiconductor switch units of the minimum of one group of switches are positioned facing each other in such a way that at least the output terminals are opposite each other.

Abstract: An autocontrol circuit for a resonance current or voltage undulator comprising a power supply, a parallel or series resonant circuit connected to the supply, and circuit elements (K.sub.1 to K.sub.4) for reversing the polarity of the resonant circuit's connection to the power supply. The power supply comprises a DC voltage generator and an inductive or capacitive element (2). The autocontrol circuit comprises circuit elements for detecting the voltages or currents of both the DC voltage generator and the output of the power supply. Differences between these two measured quantities are related to the load variations of the resonant circuit. The autocontrol circuit also comprises a comparator (11) for determining these differences, and circuit elements to use the comparator's output to produce signals which control switches (K.sub.1 to K.sub.4) which determine the polarity of the resonant circuit's connection to the power supply.
