摘要： An AC/DC conversion circuit, including: four bidirectional switches forming an H bridge; a capacitor connected between input nodes of the bridge; a capacitor connected between output nodes of the bridge; and a control 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 configuration where the first and second diagonals are respectively non-conductive and conductive, the control circuit being capable, during a phase of transition between the first and second configurations, of: turning off the switches of the first diagonal; and for each switch of the second diagonal, turning on the switch only when the voltage thereacross takes a zero value.
