ABSTRACT:
A clock-controlled frequency converter has a device for current limitation operating on the basis of chronological shortening of turn-on pulses and a further device for current limitation. As a result of the further current limitation device, the frequency converter manages without omitting turn-on pulses since the switching frequency of the frequency converter is diminished. The frequency converter can be advantageously employed in a clocked commercial lines-operated and battery-operated devices.
