Simulation slowed down by universal bridge diode rectifier
I’m doing a simulation in Matlab Simulink using Simscape Electrical Specialized power systems. The aim of my simulation is to model a synchronous machine with brushless excitation. The brushless excitation requires a rotating rectifier bridge, modelized in my simulation using the block "universal bridge". The addition of this block considerably slows down my simulation (i need 3 of them in my system), to the point that 5s of simulation can take hours.
I also created my block of the diode bridge rectifier using diodes from specialized power systems but i have the same problem.
The solver I’m using is ode23tb with a max step size 1e-3, relative tolerance 1e-3 ( in order to have correct waveforms I should use at least 1e-4, 1e-4 but it would make the simulation slower). I already tried accelerator and rapid accelerator without any improvements.
Does anyone have any syuggestion on how to resolve this simulation speed problem?I’m doing a simulation in Matlab Simulink using Simscape Electrical Specialized power systems.
