TL;DR: In this article, the fundamental limitations of neutral point voltage balancing problem for different loading conditions of three level voltage source inverters are explored and quantified using a new model in DQ coordinate frame utilizing current switching functions.

TL;DR: This paper describes the effect of interleaved discontinuous space-vector modulation (SVM) in paralleled three- phase systems using three-phase pulsewidth modulation (PWM) rectifiers as an example and uses a SVM without using zero vectors to eliminate the cause of pure zero-sequence current for parallel operation.

TL;DR: In this article, an alternative forbidden region for Z/sub 0/Z/sub i/ is proposed, based on which individual impedance specification for each load is defined, and theoretical verification, accompanied with simulation results, shows that the proposed impedance specification is a sufficient condition for small signal system stability.

TL;DR: In this article, a DC distributed power system, the interaction between individually designed power modules/subsystems may cause the instability of the whole system in the small-signal sense, these kinds of interactions can be predicted by checking impedance ratio Z/sub o/Z/sub i and can also be prevented by making impedance specification for power module/subs.

TL;DR: In this article, the problem of input filter interaction in three phase AC-DC converters from a multivariable perspective is analyzed and a sufficient condition for stability based on the singular values of the filter output impedance and converter input admittance matrices is derived.
