Abstract: A voltage converter circuit including a primary side circuit including four transistors connected in series between two voltage application nodes, and two capacitors coupled in series between the two voltage application nodes. A flying capacitor is connected between first circuit node and a second circuit node, where the first circuit node is between the first and second transistors in the transistor series, and the second circuit node is between the third and fourth transistors in the transistor series. A primary side transformer is connected between a third circuit node and a fourth circuit node, where the third circuit node is between the second and third transistors in the transistor series, and the fourth circuit node is between the first and second capacitors in the capacitor series.
