DC VOLTAGE CONVERTER Russian patent published in 2014 - IPC H02M3/07 

FIELD: electricity.

SUBSTANCE: device has input (3), output (4) and common terminals, two identical single-cycle converters (1) and (2) connected in parallel at the input and the output, each having n capacitors (6) and two groups of two-way switches, wherein the first switch (7) of the first group is connected between the positive terminal of the first capacitor and the output terminal (4) of the converter, (n-1) switches (8) of the first group, each connected between unlike terminals of capacitors of corresponding neighbouring circuits, the last switch (9) of the first group which connects the input terminal (3) with the negative terminal of the last capacitor. Each switch of the second group connects the negative terminal of the corresponding capacitor with the common terminal (5) of the converter. The device includes n two-way switches, each connecting the positive terminal of the corresponding capacitor with the input terminal (3). The converter is bidirectional and can operate in both directions, in both the output voltage increase mode and output voltage decrease mode, and as a system for exchanging electrical energy between direct current sources with multiple voltages.

EFFECT: broader functional capabilities.
