<p>FIELD: electricity. ^ SUBSTANCE: multilevel autonomous voltage inverter comprises DC link with multi-winding power transformer, unit of rectifiers and serially joined capacitors; valve sections with two arms, bridge rectifier. Each arm comprises serially joined keys with reverse diodes and pairwise joined blocking diodes. ^ EFFECT: by addition of bridge rectifier and new circuits of connection of reverse diodes and bridge rectifier, power losses are reduced, and coefficient of device efficiency is increased. ^ 4 dwg</p> |
