Dear friends I have been using SIMULINK for some time already... I am impress with the new toolboxs and ready blocks. Therefore, I wanted to simulate a simply load commutation, using a simple configuration of an LCI ( Load Commutated Inverter) please check picture attached. I think by using the speed of the motor (which can be taken from Motor simulink ready block) and knowing the initial position of the rotor, can be a good control signal to trigger the thyristor. But this is not my goal, I think that with this any mosfet configuration is good enough. I want to build a simple model which "provide" the load-commutation from the emf of the rotor. I think only applies to Synchronous Motors. ( Perhaps in Synchronous generators during braking ? ) Right now I am only introducing my idea here. If someone would like to give a try to this I will be happy to follow this post and I am sure that together we can come up with something.
