What is it about?
This paper integrates the concept of zero-sequence signal with that of one-cycle control (OCC) for easily obtaining different operation features with a three-phase rectifier. For that a generalized control strategy allows for operation in both continuous and discontinuous pulse-width modulation. The introduction of a lead-lag compensator compensates any displacement angle inclusive those introduced by large inductors resulting in that angle elimination and improvement of grid power factor control.

Why is it important?
It consists in an alternative and systematic way for allowing the one-cycle control strategy to have features equivalent to different pulse-width modulation techniques, such as continuous and discontinuous modulations with improvement of the power factor.
Perspectives
I hope this this paper interest people who works with power factor control and system that use rectifiers such as universal active filters.
