VOLTAGE CONVERTER Russian patent published in 2012 - IPC H01L25/07 

FIELD: electricity.

SUBSTANCE: multisectional voltage converter comprises at least one phase output connected to opposite poles of DC converter voltage, and subsequent connection of switching elements, besides, each switching element has at one side at least two semiconductor chips, and at the other side there is at least one capacitor that accumulates energy. The middle point of the serial connection forms a phase output, which is configured with the possibility of connection to the side of AC converter voltage and division of phase output into a branch of upper valves and a branch of lower valves. The semiconductor chips of switching elements are arranged in packets comprising at least two chips. The converter comprises a layout, for application of pressure to opposite ends of each packet for provision of electric contact between chips in the packet. Chips have plate structure and are arranged so that their larger sides are directed towards continuation of the packet. At least two semiconductor chips are related to one switching element, and adjacent chips related to one switching element are divided by a metal plate for provision of electric contact.

EFFECT: invention makes it possible to create an improved voltage converter with increased reliability of connections.
