  • AC-DC converter comprising a filtering device
    Patent number: 5574635
    Abstract: The converter comprises a rectifier circuit, choppers, chopper control circuits and an input filter of LC type. The control circuits comprise loops regulating the output voltages and the currents of the choppers, and a loop regulating the current flowing in the filter and rectifier. This additional regulation enables oscillations generated in the input filter by the current steps to be dampened. The values of the positive and negative components of the currents in the input filter and rectifier are supplied to the control circuits by sensors.
