A voltage stabilizing module for multi power source input is compatible with multiple input power sources including DC power source and/or AC power source and comprises a plurality of receiving ends, a power source selection unit and a voltage conversion unit. The receiving ends receive the input power sources. The power source selection unit is coupled with the receiving ends to receive the input power sources and sets at least one of the input power sources as a working power source. The voltage conversion unit receives the working power source and keeps the working power source at a working voltage level to act as a voltage signal outputted to a loading.

Fan system and voltage stabilizing module for multi power source input

A fan includes a motor control device which is electrically connected with a motor and an alternating current power source. The motor control device includes a converting circuit, a power factor correction circuit and a motor controlling circuit. The voltage of the alternating current power source is converted to be direct current voltage by the converting circuit and the power factor correction circuit, and then the direct current voltage is outputted to the motor control circuit. The motor controlling circuit generates a driving signal in accordance with the direct current voltage for driving the motor to operate.
