To the end of providing a constant AC voltage to a variable load ( 1 ) which is arranged remote of a voltage source ( 3 ), a voltage drop over an electrical supply line ( 2 ) which connects the load to the voltage source ( 3 ) is compensated for by a compensation AC voltage which, if added to the constant AC voltage, results into the output AC voltage U<SUB>full </SUB>of the voltage source ( 3 ) and the value of which is varied depending on the absolute value of the alternating current (I) conducted to the load ( 1 ) and on the phase angle phi between the output AC voltage U<SUB>full </SUB>of the voltage source ( 3 ) and the alternating current (I).
