A switching converter comprises first, second, third and fourth main switches. The first main switch (S m,1 ) is connected between a positive input terminal (V in + ) and a first node (M). The second main switch (S m,2 ) is connected between the first node (M) and a negative input terminal (V in - ). The third main switch (S m,3 ) is connected between the positive input terminal (V in + ) and a second node (L). The fourth main switch (S m,4 ) is connected between the second node (L) and the negative input terminal (V in - ). The switching converter also includes a first auxiliary switch (S a,1 ) connected between the first node (M) and a third node (K); a second auxiliary switch (S a,2 ) connected between the second node (L) and a fourth node (J); a first main inductor (500a) connected between the first node (M) and a negative output terminal (V out - ); a second main inductor (500b) connected between the second node (L) and a positive output terminal (V in + ); and an auxiliary inductor (502) connected between the third node (K) and fourth node (J). |
