Abstract
A road construction machine, particularly a road finisher or a feeder for a road finisher, with a primary drive unit including at least one combustion engine driving a three-phase generator, and further including at least one connection means for at least one conventional alternating current standard consumer, at least one stabilized voltage supply unit is connected between the connection means and the three-phase generator, wherein the voltage supply unit provides standard mains voltage with a permanently stable frequency at the connection means independent of the speed of the combustion engine driving the three-phase generator.
Claims5
A road finisher or a feeder for a road finisher with a primary drive unit, comprising a combustion engine driving at least one three-phase generator, and
- at least one connection means for at least one conventional alternative current consumer,
- a stabilized voltage supply unit having at least one universal conversion circuit including a bridge rectifier or an intermediate circuit containing a controlled power supply for generating an intermediate voltage and a standard mains voltage with a permanently stable frequency from the intermediate voltage connected between the connection means and the three-phase generator to provide the standard mains voltage at the connection means which is connected via a connection line to the universal conversion circuit.
