The input choke acts as a harmonic filter and is installed at the input of the variable frequency drive (inverter). It suppresses harmonics from the power supply or those generated by the inverter itself, and reduces input voltage spikes, helping provide filtered voltage and an improved power factor.
It helps protect the inverter and motor and ensures safer operation.
