1. A hybrid power supply device of an air-conditioner, for supplying electric power to a DC rail of an inverter of a DC brushless motor of the air-conditioner to provide a multiple of power sources to the DC brushless motor, and the hybrid power supply device comprising:

  • a first power source input end, connected to an grid AC power of utility power;

    a second power source input end, connected to a power source that supplies an AC power or a DC power;

    a first one-way rectifier, including a plurality of diodes, and having an input terminal connected to the first power source output end, and an output terminal connected to the input terminal of the inverter for providing a first DC output to the DC rail of the inverter; and

    a second one-way rectifier, including a plurality of diodes, and having an input terminal connected to the second power source output end, and an output terminal connected to the output terminal of the first one-way rectifier for providing the second DC output to the DC rail.
