  • CONVERTING CIRCUIT
    Publication number: 20160241161
    Abstract: A current converter circuit arrangement, and a current converter device embodying such arrangement, having positive and negative potential voltage connections, a neutral connection, an AC voltage connection, and first and second inductances. The arrangement further has at least six power semiconductor switches, to each of which a diode is electrically connected back-to-back in parallel, and two further diodes, for a total of eight. The inventive current converter circuit arrangement requires only a low number of power semiconductor switches, at a minimum six, to generate at least five voltage levels at the AC voltage connection.
