Circuit board, defining a plurality of switching arms connected in parallel so as to convert a first voltage into a second voltage, at least one of which is DC voltage. The board includes a plurality of controllable electronic switches mounted pairwise in series on either side of a midpoint, so as to produce the switching arms connected in parallel. A plurality of decoupling capacitors are connected in parallel to one another, and in parallel to the DC voltage. Two electrically conductive layers are arranged parallel to one other, one of which is at the highest potential of the DC voltage and the other of which is at the lowest potential of the DC voltage. Each of the decoupling capacitors having one terminal connected to one of these electrically conductive layers and its other terminal connected to the other of these electrically conductive layers.

Electronic board for voltage converter

An electrical circuit for charging a DC voltage source from an AC voltage network. The circuit includes an input that is able to receive an AC voltage from the voltage network, and a first output able to be connected to the DC voltage source. An insulating stage formed using a plurality of capacitors is arranged so as to electrically insulate the input from the first output of the circuit. A frequency-raising stage is arranged between the input of the circuit and the insulating stage so that the capacitors of the insulating stage are in a circuit portion that has flowing through it an AC current at a frequency that is greater than that of the AC network.
