Abstract
PURPOSE: To reduce a level of noise at a low speed range by controlling a driving power source for an electric blower utilizing control factors such as a vehicle speed.
CONSTITUTION: A vehicle speed, load currents of electrical units 2, forward step notch number and circumferential temperature are input to a controlled power supply unit 1 as control factors. The unit 1 calculates the minimum number of rotations of electric blowers 3 necessary for cooling respective electrical units 2 by using specified functions and then transmit the required driving power to the electric blowers 3 as output signals. By so doing, noise generated at a low speed range can be lessened and power consumption can be saved.
