Abstract
Unique systems, methods, techniques and apparatuses of an active neutral point clamped converter (ANPC converter). One exemplary embodiment is a power conversion system comprising a grid-side converter, a DC link, a multi-phase ANPC converter coupled to an electric machine, and an electronic control system. The electronic control system is structured to selectably operate in a first mode and a second mode in response to a device failure state of the ANPC converter, the first mode operating the grid-side converter to provide a first DC link voltage and operating the ANPC converter using a first modulation index, and the second mode operating the grid-side converter to provide a second DC link voltage greater than the first DC link voltage and operating the ANPC converter using a second modulation index lower than the first modulation index.
