How does a DC power source work in a three-phase inverter?

The DC power source of the three-phase current-type inverter, i.e., the DC current source, is achieved through a variable voltage source using current feedback control. However, employing only current feedback cannot reduce the power ripple in the inverter input voltage caused by switch actions, resulting in current fluctuations.

What is a three-phase current-type inverter?

Similar to the three-phase voltage-type inverter circuit, the three-phase current-type inverter consists of three sets of upper and lower pairs of power switching elements. However, the switching method is different from the voltage-type. The inclusion of a large inductance L in series with the DC input minimizes fluctuations in the DC current.
