Description

Compressor and air conditioner
Technical Field
The invention relates to the field of compressors, in particular to a compressor and an air conditioner.
Background
The front stage of the frequency converter of the household air conditioner is an uncontrollable rectifier for single-phase power frequency alternating current input, and the bus capacitor stabilizes the bus voltage by using a large electrolytic capacitor. However, large electrolytic capacitors are bulky and have a limited lifetime, which greatly limits the miniaturization and lifetime of the system. Moreover, 3C certification in China clearly prescribes that for household air conditioning systems with each phase of current less than 16A, the harmonic limit value of each sub-current must meet the class A standard of IEC 61000-3-2. Therefore, in order to improve the network side current quality, the air conditioning system with a large electrolytic capacitor needs to add a power factor correction circuit, which in turn increases the loss and cost of the system. If a small capacitor is used, the corresponding compressor cannot meet the requirement of electric control due to limitation, and the system cannot stably and reliably operate.
