METHOD OF SERIES CONNECTION OF ADDITIONAL DIRECT CURRENT SOURCES FOR VOLTAGE LEVELING IN NETWORK WITH LOAD INCREASE Russian patent published in 2021 - IPC H01M2/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment. Method of series connection of additional direct current sources for voltage leveling in the network at load increase includes the following stages: connecting by wires first load between positive and negative terminals of source DC source, observing polarity, wherein one of wires connected to negative terminal of source DC source is common negative wire, and other of wires connected to positive terminal of source DC source, is common positive wire. First additional DC source is used to equalize the voltage value in the network when connecting the load exceeding the rated power of the primary DC source, and connecting the negative terminal of the first additional direct current source to the positive terminal of the source direct current source, wherein the initial and the first additional direct current sources form the first group of sources, wherein the negative terminal of the source DC source and the positive terminal of the first additional DC source are outputs of the first formed group of sources. K-th additional direct current source is used to equalize the voltage value in the network when connecting the load exceeding the used rated power (K-1) of the source group, and connecting the negative terminal of the K-th additional direct-current source to the positive terminal (K-1) of the additional direct-current source, wherein the initial, first, second ... and K-th additional DC sources form the K-th group of sources, at that, the negative terminal of the source DC source and the positive terminal of the K-th additional direct current source are outputs of the K-th formed group of sources. N-th load BN is connected between common positive and common negative wires, at the same time positive terminal of K-th formed group of sources is connected to common positive wire in N-th load connection point.

EFFECT: technical result consists in improvement of system efficiency with respect to voltage equalization in DC network at connection of load exceeding used rated power of DC source.
