Abstract
The present description concerns a converter comprising an AC-DC conversion stage comprising a first thyristor, a first power supply circuit delivering a first reference voltage between a first node and a second node, and a second power supply circuit delivering a second reference voltage between third and fourth nodes, the cathode of the first thyristor being coupled to the first node of the first power supply circuit by a first switch and being connected to the fourth node, the second power supply circuit comprising a first rectifying element coupled to the second node of the first power supply circuit and coupled to the third node.
