Decomposition Method for Event-Detection State Vector Simulation of Switched-Mode Power Supplies

This work presents a new method for the state vector simulation of switched-mode power supplies using decomposed matrices. With this method, switching instances are updated reliably from previously computed values, providing a highly efficient means for event-detection state vector simulation. The method is demonstrated on a 23
^rd
-order state-space piecewise linear model of a boost converter with and without control feedback, resulting in a several of orders of magnitude speed-up of the simulation, relative to the same device simulated in LTspice or PLECS.
