Abstract:
Disclosed examples include power conversion systems, methods and computer readable mediums to operate an inverter to drive a motor load through an output filter, in which a control output value is computed according to a current reference value and a current feedback value using a proportional-integral (PI) current regulator, the control output value is filtered using a lag compensator filter to compute an inverter output command value, and the inverter is controlled according to the inverter output command value.
