Abstract

Fast long-term dynamic simulation of power converters is discussed. Because of switching actions, the converter can operate in different configurations and, therefore, it can be represented by a state-space time-varying linear system. This paper presents a new method for calculating switching time from an accurate and explicit form of the switching condition, hence the step-by-step search of the switching instant can be greatly simplified. In the proposed algorithm, a converter is partitioned into subsystems, which are simulated in a decoupled manner and coordinated through data exchange
