Problems solved by technology

[0002] Inverter air conditioning system is mainly composed of rectifier, electrolytic capacitor, power module and control module, in which the control module detects the voltage and current signal of the compressor, determines the control voltage through the vector control algorithm, and determines the modulation signal and The power module drives the variable frequency compressor to work stably at the predetermined frequency. The power module is turned on or off to cause energy loss, and the los

Abstract

The invention provides a control method of an inverter compressor, a control system of the inverter compressor, an air conditioner, computer equipment and a computer readable storage medium. The method comprises the following steps: acquiring output current of the inverter compressor in real time; calculating the time of duration of the output current which is continuously greater than preset current; and when the time of duration is greater than a time threshold value, controlling the inverter compressor to stop or reducing carrier frequency. By controlling the inverter compressor to stop orreducing the carrier frequency, energy loss of a power switch is reduced when the inverter compressor is in an overload situation, the circumstances that the temperature of the power switch is over high and thus the power switch is damaged are avoided, and meanwhile, the circumstance that ageing of the inverter compressor is accelerated and the inverter compressor is even damaged due to over-longoverload running time is avoided.
