摘要

Dc-dc converter with bipolar output and use thereof for the connection of a distributed generation system to a bipolar dc network. The dc-dc converter (10) has an input for the connection of a dc source with monopolar output (9) and a bipolar voltage output, with the same voltages but with opposite polarities. The dc-dc converter (10) comprises three inductors (l1, l2, l3), four capacitors (c1, c2, c3, c4), two diodes (d1, d2) and a power switch (11) as a switching device. The main advantage of this topology is to use a single switching device to obtain a balanced bipolar output. In addition, the control terminal of the power switch (11) is connected to ground, which simplifies the design of the door drive device of the power switch (11).
