Definitions
- the present disclosure relates to an air conditioner, and more particularly, to an apparatus for controlling a driving of an air conditioner having modularized components.
- an air conditioner drives a compressor by using a three-phase motor.
- An alternating current of commercial power is converted into a direct current by a power supply unit of the three-phase motor, and then the converted direct current is reconverted into an alternating current by an inverter.
- the re-converted alternating current is applied to the three-phase motor, thereby driving the three-phase motor.
- FIG. 1 is a configuration view showing an apparatus for controlling a driving of an air conditioner in accordance with the conventional art.
- the conventional apparatus for controlling a driving of an air conditioner comprises a converter 110 having an active filter 111 and a smoothening capacitor C, for converting an alternating current (AC) voltage of an AC power into a direct current (DC) voltage; an active filter controller 120 for removing harmonics and enhancing a power foctor by controlling an operation of the active filter 111 at a zero crossing point of the AC voltage; and an inverter 130 for converting a DC voltage converted by the converter 110 into an AC voltage thereby supplying the AC voltage to a three-phase motor 140 for driving a compressor.
- AC alternating current
- DC direct current
- the active filter 111 includes a reactor L, a diode rectifier and power semiconductor devices Ql and Q2, and converts a waveform of an inputted alternating current into a sine wave almost similar to a phase of an inputted AC voltage.
- the smoothening capacitor C smoothens an AC voltage rectified by the diode rectifier of the active filter 111 into a DC voltage.
- the active filter controller 120 includes a synchronization signal generator 121 connected to an output port of AC power, for generating a synchronization signal when an AC voltage of the AC power passes through a zero crossing point; and a controlling circuit 122 for generating a driving signal to remove harmonics and to enhance a power fector by turning on/off the power semiconductor devices Ql and Q2 of the active filter 111 based on a synchronization signal outputted from the synchronization signal generator 121.
- An alternating current (AC) voltage cutputted from AC power is inputted to the converter 110 via the reactor L connected to the output port of the AC power so as to enhance a power factor and to reduce harmonics.
- the AC voltage inputted to the converter 110 is rectified by the diode rectifier of the active filter 111, and then is smoothened by the smoothening capacitor C.
- the active filter controller 120 controls an operation of the power semiconductor devices Ql and Q2 of the active filter 111 when an AC voltage passes through a zero crossing point, thereby enhancing a power factor of the converter 110 and reducing harmonics. That is, the synchronization signal generator 121 of the active filter controller 120 generates a synchronization signal when the AC voltage passes through a zero crossing point. Then, the controlling circuit 122 generates a driving signal (i.e., a power f ⁇ ctor enhancing pulse and a noise reducing pulse) based on the synchronization signal, thereby turning on/off the power semiconductor devices Ql and Q2 of the active filter 111.
- a driving signal i.e., a power f ⁇ ctor enhancing pulse and a noise reducing pulse
- the inverter 130 converts a DC voltage smoothened by the smoothening capacitor C into an AC voltage, and outputs the AC voltage to the three-phase motor 140 for driving a compressor. Accordingly, an rpm of the three-phase motor 140 is controlled according to a frequency of the AC voltage.
