Abstract
A power conversion system and controller configured to generate a real average DC current reference based on a DC bus voltage of a DC link circuit and a DC bus voltage setpoint, generate real and reactive ripple current references based on the DC bus voltage of the DC link circuit and a ripple angle of the DC link circuit, and generate rectifier switching control signals to operate rectifier switching devices based on the real average DC current reference and the real and reactive ripple current references.
