Abstract:
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.

Claim (Index 1):
An AC-voltage-to-DC-voltage conversion circuit, comprising:\n four first bidirectional switches forming a first H bridge having first and second input nodes and first and second output nodes, the first and second input nodes of the bridge being respectively directly coupled to first and second nodes of application of the AC voltage; a first capacitor connected in parallel with the first bridge between the first and second input nodes of the bridge; and a control circuit capable of controlling the bridge alternately to a first configuration where the switches of a first diagonal of the bridge are on and the switches of a second diagonal of the bridge are off, and to a second configuration where the switches of the first diagonal are off and the switches of the second diagonal are on, the control circuit being capable, during a phase of transition between the first and second configurations, of successively: turning off the switches of the first diagonal; and for each switch of the second diagonal, monitoring the voltage across the switch and turning on the switch only when the voltage thereacross takes a zero value.
