Abstract
The present invention relates to a near zero current-ripple inversion circuit including top and bottom cells, a transformer (T) comprising primary windings (P, P) and a secondary winding (S), and at least one middle cell connected in series between the top and bottom cells. The top cell comprises two capacitors (C, C) and a switch (Q) each connecting to the middle cell, and an inductor (Lr) and the primary winding (P) connected in series between the capacitor (C) and switch (Q), wherein the switch (Q) is connected to the capacitors (C, C) respectively. The bottom cell comprises a capacitor (C) and a switch (Q) each connecting to the middle cell, and an inductor (Lr) and the primary winding (P) connected in series between the capacitor (C) and switch (Q), wherein the primary winding (P) is connected to the middle cell, and the capacitor (C) and switch (Q) are connected.
