The circuit comprise a switch controlled so that at each period of the AC voltage it is conducting for a period of time which depends on the desired output voltage, and a control of the output voltage slaved to an instruction or reference signal. The measuring signal of the control is the mean value of the voltage at the terminals of said switch during a period of the AC voltage. For establishing the mean value there is provided, an integrator whose input receives the voltage signal at the terminals of the controlled switch.
