INVERTER Russian patent published in 2015 - IPC H02M7/48 H02P1/04 

FIELD: electricity.

SUBSTANCE: invention is related to inverter, which receives DC power from the common DC bus (15) and excites the load. Configuration is so that a switching element (SW1) is installed in the first current path, wherein current passes through DC output (P) at the positive side during supply of power, a bypass diode D1 is installed in the second current path, wherein current passes through DC output (P1). A charging resistor (R1) is installed in the third current path, wherein current passes through DC output (P) at the positive side when a smoothing capacitor of the smoothing module (13) is charged initially and a breaking resistor (R2) is coupled externally between DC outputs (P and P1) at the positive side so that DC output (P) at the positive side becomes an end, which potential is identical to potential of the bus (15a) at the positive side of the common DC bus (15).

EFFECT: potential connection of the low-capacity inverter to the load of high capacity.
