The invention provides a compressor control circuit, an air conditioner compressor control method and an air conditioner. By arranging an electric reactor provided with a plurality of taps in a power supply circuit of a compressor, and connecting a plurality of subsidiary control units into a control unit, part of or all of windings of the electric reactor can be controlled to be connected into a compressor electric control circuit when the compressor is started, and harmonic generated during operation of the compressor can be filtered, so that the problems that under a low input voltage situation, since all the windings of the electric reactor are connected into the compressor electric control circuit when the compressor is started, voltage is divided, the work voltage loaded on the compressor is lowered, and the compressor is started abnormally are solved; and meanwhile, the windings of the electric reactor can have the effect of filtering the harmonic generated during operation of the compressor when the compressor is started, and the reliability of the compressor control circuit is improved.
Description
technical field [0001] The invention relates to the field of air conditioner control, in particular to an air conditioner compressor control circuit, an air conditioner compressor control method and an air conditioner. Background technique [0002] The air conditioner works under relatively harsh working conditions, such as areas with high ambient temperature that require the cooling capacity to meet the requirements. At this time, the power of the compressor that needs to be matched is larger than that under other normal working conditions, and the compressor continues to work at a high current state. Harmonic interference will be generated. For some areas with strict EMC requirements, in order to pass the IEC EMC harmonic current standard, some air conditioners need to add a reactor circuit with a certain inductance to filter the harmonics. Pass the harmonic current test, but due to the increase The inductance of the reactor will cause partial voltage when the compressor s...
