POWER CELL WITH PRINTED CIRCUIT BOARDS AND DECOUPLER AND MULTICELL POWER SUPPLY MEDIUM VOLTAGE SOURCE Russian patent published in 2019 - IPC H02M9/06 H02M7/00 

FIELD: electricity.

SUBSTANCE: inventions relate to power cells with printed circuit boards (PCB) and decoupler and to multicell power sources of medium voltage. Technical result is achieved due to that proposed power cell (100) with PCB for location in multi-source power source (500) includes housing assembly (102) containing non-conductive material, with multisection housing (104, 106), and PCB assembly (120) located inside housing assembly (102), which are configured to provide built-in insulation by voltage of power cell (100). Outside housing assembly on front side of power cell (100) there are input fuses (132) for protection against overcurrent either in source circuit or in load circuit, functionally connected to three-phase input (130) of alternating current, located in housing assembly (102) of power cell (100), as well as shunting mechanism (142), allowing to bypass the failed power cell in a multi-cell power source, in which power cells are connected in series in each group of phases, and continue operation of multicell power source (500) at low load, and functionally connected to alternating-current single-phase output (140) located in unit (102) of housing of power cell (100).

EFFECT: providing a compact power supply, in which the voltage decoupling is built into separate power cells, and is not part of the power supply source structure, which enables closer arrangement of power cells to each other.
