Method for improving availability of a fan system

The method involves driving the drive via a drive module that drives power switches connected to an electronic circuit board with a pulse width modulation signal (27) by changing the instantaneous duty cycle to modified a maximum duty cycle (22) on reaching a first threshold temperature (24) and to...

Summary:The method involves driving the drive via a drive module that drives power switches connected to an electronic circuit board with a pulse width modulation signal (27) by changing the instantaneous duty cycle to modified a maximum duty cycle (22) on reaching a first threshold temperature (24) and to a minimum value (21) on reaching a higher threshold temperature (26).
