Abstract
An AC/DC converter including: an H bridge; an inductance in series with an input of the bridge; an inductance in series with an output of the bridge; and a circuit capable of controlling the bridge alternately to a first configuration where first and second diagonals of the bridge are respectively conductive and non-conductive, and to a second complementary configuration, the circuit being capable, during a phase of transition between the first and second configurations, of: turning on a first switch of the second diagonal; turning off a first switch of the first diagonal when the current flowing through this switch takes a zero value; turning on the second switch of the second diagonal; and turning off the second switch of the first diagonal when the current flowing through this switch takes a zero value.
