This paper introduces an optimization based approach towards steady-state analysis of switched power electronic systems. The convergence performance of the optimization is improved by the estimation of the state variables in steady-state. Accurate state variable estimation can be achieved by previously simulating a set of multi-resolution approximations - averaged models of the original topological...
This paper studies the switching sequences for Neutral-Point-Clamped SVPWM. Generalizes the combinations of three-segment switching state sequences, rules for minimizing the switching losses, and for the avoidance of 2-level phase voltage change are given. The PWM scheme using these rules is devised for eliminating even order harmonics in asymmetrical uniform sampling. Simulation results prove the...
This paper details a technique in the time domain for the fast periodic steady-state solution of systems including flexible AC transmission systems (FACTS) based on sinusoidal pulse width modulation (SPWM); two models for the practical representation of their voltage source converters (VSC) are used. The computation of the periodic steady-state solution of power systems including FACTS is efficiently...
This paper describes an implementation of a 3-phase voltage sourced regenerative rectifier under direct current control strategy. General mathematical model of the converter is first established. Based on the model, the principle of the direct current control strategy is presented, simulation results are given, and circuit operations in steady state are analyzed. Based on SVPWM, the analysis explains...
