摘要（英）：

The present invention refers to a system for streamlining energy efficiency, for application in cooling equipment compressors. Said system has at least a main circuit of the frequency inverter (10) and an electric energy power source (FAC) electrically associated to each other. The main circuit of the frequency inverter (10) comprises at least a wave rectifier (4). In addition, the main circuit of the frequency inverter (10) comprises at least a bus capacitor (CB), electrically associated in parallel to the wave rectifier (4) and to the compressor, electrically chargeable by a charge current. Additionally, the main circuit of the frequency inverter (10) comprises at least a passive component (P), electrically associated to the wave rectifier (4), capable of reducing a charge current of the bus capacitor (CB) and/or attenuating the harmonic content of an input current coming from the electric energy power source (FAC). Said system comprises at least a means of obtaining power in an input of the main circuit of the frequency inverter (10). Further, said system comprises at least a control unit (3) operatively associated to the means for obtaining power. Said main circuit of the frequency inverter (10) is provided with an active switch (K) electrically associable in parallel to the passive component (P), and the control unit (3) is arranged so as to permit the drive of the active switch (K) based on the power at the input of the main circuit of the frequency inverter (10). The present invention also refers to a method of streamlining energy efficiency, for application in cooling equipment compressors.
