Abstract

A converter including a DC voltage source; a transformer; a bridge circuit including first and fourth transistors in a first leg and second and third transistors in a second leg and controlled such that, when current flows in the first leg, current does not flow in the second leg and such that, when current flows in the second leg, current does not flow in the first leg; and a flux balance circuit arranged to measure the currents in the first and second legs and to control a dead time of the first, second, third, and fourth transistors based on the measurement of the currents in the first and second legs so that the currents flowing in the first and second legs are equal or substantially equal.
