A sequence components model of the AC/DC converter in the harmonic domain

In the steady state, the AC/DC power converter couples harmonics on the DC side with sequence component harmonics on the AC side. A solution for the power converter in sequence components may be more efficient than one in phase components. Since most other power system steady-state analysis is framed in sequence components, so too must the power converter analysis be-if a unified solution is to be achieved. However in order to model the commutation process, existing power converter models suitable for iterative steady-state analysis are necessarily framed in phase components. When the power converter steady-state is solved by Newton´s method, the advantages of both frames of reference can be derived by a judicious use of the sequence transform, interfacing a Newton solution in sequence components, to a power converter model in phase components
