Reinjection concept: a new option for large power and high-quality AC–DC conversion
IET Power Electronics, 2008 A new concept referred to as reinjection AC/DC conversion is described, applicable to both self- commutating voltage source and current source conversions. It combines all the benefits of the multi-level, soft switching and ripple reinjection concepts. The aim is to achieve high-quality waveforms, simplify the structural configuration and the interface
