DISTRIBUTING DEVICE ELEMENT AND CONVERTER CIRCUIT FOR SWITCHING MANY VOLTAGE LEVELS WITH SUCH DISTRIBUTING DEVICE ELEMENT Russian patent published in 2009 - IPC H02M7/48 H02M3/07 

FIELD: electricity.

SUBSTANCE: present invention can be used in electrical engineering. The element for a distributing device contains a group of connections (1), comprising six bidirectional power semiconductor switches (2, 3, 4, 5, 6, 7) and a capacitor (25). The first switch (2) is connected anti-parallel and in series with switch (3). The third switch (4) is connected anti-parallel and in series with switch (5). The capacitor (25) is connected with the point of connection of the first switch (2) and the second switch (3) and with point of connection of the third (4) and fourth (5) switches. The fifth switch (6) is connected to the point of connection of the first (2) and second (3) switches, and with the fourth switch (5). The sixth switch (7) is connected to the point of connection of the third (4) and fourth (5) switches and with the second switch (3). There are first and second series-connected capacitors (8, 9). The first switch (2) and the third switch (4) are connected to each other at the point of connection of the fist (8) and second (9) capacitors. Proposed also is a converter circuit for switching many voltage levels, containing the said element of a distributing device.

EFFECT: reduced amount of accumulative electrical energy and decrease in dimensions.
