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. Each arm comprises serially joined keys with reverse diodes and pairwise joined blocking diodes. Reverse diodes are joined into two groups, and some of their electrodes are connected to according keys, and others are joined to each other and connected to output clamps of DC link.
EFFECT: reduced power losses and increased efficiency of device.
