Abstract :
This paper presents a study on an interpolation algorithm capable of handling multiple switching during one time step in fixed time step simulation of pulse-width modulated (PWM) power converters. The proposed algorithm is analyzed and implemented in Simulink´s SimPowerSystems simulation engine. Simulation results obtained with a test system consisting of a variable-speed wind-turbine-driven permanent-magnet synchronous generator are presented. The algorithm is evaluated by comparing the obtained results with those produced by a small time step simulation.
