Abstract (en)
[origin: WO2008095565A1] The invention relates to a fan arrangement and a method for operation thereof, comprising a control module (1) for controlling two circuit breakers, two circuit breakers (3, 4), two electric motors (5, 6) which have their operating voltage U<SUB>B</SUB> supplied to them via the circuit breakers (3, 4), and at least one temperature sensor (8) on a board (2) on which the circuit breakers (3, 4) are located, with the control module (1) having means for evaluation of a signal T<SUB>NTC</SUB> from the temperature sensor (8) and for setting the duty ratios TV<SUB>1</SUB>, TV<SUB>2</SUB> of pulsed control voltages at the circuit breakers (3, 4), taking account of this signal T<SUB>NTC</SUB> as well as a requested fan power, such that no power loss P<SUB>V</SUB> greater than a predetermined value occurs in any power component (3, 4, 7).
