摘要： A power circuit has an input circuit for coupling to a power supply to receive input current. One or more fans are driven with current pulses from an output circuit. Commutation noise from the current pulses back to the power supply is minimized. The commutation noise may be minimized by providing an isolated current source, by staggering the phase of pulses to multiple motors to increase the frequency and filter out the commutation noise, or by a combination thereof.
