VOLTAGE CONVERTER Russian patent published in 2012 - IPC H02M7/49 

FIELD: electricity.

SUBSTANCE: voltage converter of M2LC type has serial connection of switching cells (7), besides, each switching cell has at one side at least two semiconductor assemblies connected in series and each comprising a semiconductor device of locked type and a reverse diode connected in parallel with it, and at the other side at least one capacitor that accumulates power (20). Serial connection of switching cells has the first end (61), connected to a pole (5) of DC voltage with high potential, and an opposite end (62), connected with a phase output (10) of the converter. A layout (70) is configured with the possibility to connect the phase output (10) with the other pole (6) with a neutral potential at the side of DC voltage of the converter, and supplying voltage pulses to the phase output, which may be both positive and negative relative to the neutral potential.

EFFECT: possibility of unidirectional operation without a transformer.
