In order to smooth the current a choke can be placed upstream the inverter 2 locations possible: 
Effect of the choke
- In the DC bus
- Onto the main supply
Effect of the choke
- The efficiency of the choke on harmonics is depending on its impedance
- Higher the impedance, lower the harmonic distortion
- But higher the impedance, higher the drop voltage
