Abstract :
The long-term dynamic simulation of power converters is treated. Due to switching actions, the converter can operate in different configurations, and therefore it can be represented by a state-space time-varying linear system. A method is presented for calculating switching time from an exact and explicit form of the switching condition, which allows the step-by-step search of the switching instant to 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.<>
