The invention provides a device for producing electricity intended in particular to be stowed on board a vehicle or a container, including a three-phase alternator able to be driven in rotation at a variable speed by a thermal engine, a rectifier for generating a rectified current form the current delivered by the alternator and a voltage-booster chopper using the self-inductance of the alternator to step up the voltage. The alternator includes six or eight poles and operates with a switching frequency of preferably between 3 and 15 kHz.

Device for producing electricity having voltage-booster chopper circuit with an IGBT transistor

A device for producing electricity, the device comprising a three-phase alternator comprising three windings, a rectifier for converting the AC delivered by the alternator into rectified current, and a voltage-raising chopper using the self-inductance of the alternator to raise the voltage. The device includes a switch unit enabling the three windings to be connected either in a star configuration when the alternator is being rotated to produce electricity, or else to the respective phases of a three-phase network when the alternator is stopped.

Device for producing electricity from a three-phase network, in particular for a road vehicle

A converter for an electric motor or transformer, the converter being comprising a connection box having passages for electrical conductors and having a semiconductor electronic module removably fixed to the connection box. The electronic module has a radiator-forming box that is open at one end, at least one electronic card at least partially embedded in a resin cast inside said radiator-forming box, and at least one connector emerging from the resin. The opening of the radiator-forming box enables it to be fitted to the connection box. The connection box has at least one window giving access to the connector(s) of the electronic module.
