Abstract
A rectifying circuit including: between a first terminal of application of an AC voltage and a first rectified voltage delivery terminal, at least one first diode; and between a second terminal of application of the AC voltage and a second rectified voltage delivery terminal, at least one first anode-gate thyristor, the anode of the first thyristor being connected to the second rectified voltage delivery terminal; and at least one first stage for controlling the first thyristor, including: a first transistor coupling the thyristor gate to a terminal of delivery of a potential which is negative with respect to the potential of the second rectified voltage delivery terminal; and a second transistor connecting a control terminal of the first transistor to a terminal for delivering a potential which is positive with respect to the potential of the second rectified voltage delivery terminal, the anode of the first thyristor being connected to the common potential of voltages defined by said positive and negative potentials.
