UNIDIRECTIONAL DEVICE AND DC VOLTAGE CONVERSION AND CONTROL SYSTEM Russian patent published in 2021 - IPC H02J1/10 H02M3/28 H02M3/335 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to applied technologies of power electronics. The effect is achieved in that the unidirectional DC voltage conversion device includes an input stage circuit, a main power circuit, an auxiliary disconnector of the previous stage, an auxiliary disconnector of the subsequent stage, while the port of the previous stage is connected to the port of the subsequent stage by a cascade connection; specified auxiliary switch of the upstream stage is connected to the negative terminal of the upstream port and together with the positive terminal of the port of the upstream stage forms a first input port of said unidirectional DC voltage converting device; specified auxiliary downstream disconnector connects to a negative downstream port terminal of said main power circuit and together with a positive downstream port terminal forms a first output port of said unidirectional DC voltage converting device.

EFFECT: creation of a powerful device that meets the high working range requirements.
