Resumen:

In this article we study the performance of quantized state system algorithms in the simulation of switched mode  power supplies. Under realistic modeling assumptions, these models are stiff and exhibit frequent discontinuities, making them difficult to simulate with classic solvers. However, there are linearly implicit quantized state system  methods that can efficiently handle these types of systems, providing faster and more accurate results. In order to  corroborate these features, we first built the models corresponding to the different topologies of switched mode  power supplies, and then analyzed the resulting equation structures in order to establish whether they can be efficiently  simulated by linearly implicit quantized state system algorithms. Finally, we compared the simulation performance  of linearly implicit quantized state systems with the widely used DASSL solver. The results showed that the  linearly implicit quantized state systems were 3?200 times faster and noticeably more accurate than the differential  algebraic system solver.
