Circuit arrangement for a DC voltage intermediate circuit
Such a circuit arrangement has a mains-operated rectifier bridge which supplies the DC voltage intermediate circuit. In the DC voltage intermediate circuit, a capacitor is arranged to be charged before the switching of the rectifier bridge by means of a charging circuit from the network. To an uncontrolled rectifier provide and keep the losses in the charging circuit in view of a high repetition rate low, the charging circuit comprises at least one thyristor, which is in series with the capacitor, as well as a lying in the same forward direction branch of the rectifier bridge on the alternating voltage network. The thyristor is ignited in synchronism with the power frequency, and the ignition angle, relative to the zero crossing of the mains voltage is reduced during a plurality of mains periods.
